Description

BACKGROUND OF THE INVENTION
• (1) Field of the Invention[0001]
• The present invention relates to a file handling device, and more particularly, to a file handling device capable of improving the efficiency of manipulation on a file menu of an application, a menu of a file browser such as Explorer, and a menu of an icon on the desktop, the drag-and-drop operation on the file browser, etc. during handling of files in a GUI (Graphical User Interface) environment, that is, during selection of a file to be opened in an application, selection of a location to which a file is to be copied, and selection of an application in which a file is to be opened.[0002]
• (2) Description of the Related Art[0003]
• In GUI environments, files are handled basically with the use of a mouse, and almost all operations except for the entry of characters, such as the selection of a data file to be opened from within an application and the operation of selecting, copying or moving files listed in a file browser, can be performed with the mouse.[0004]
• In an operating system based on a GUI environment, for example, in Windows (trademark of Microsoft Corporation, U.S. A., registered in the United States and other countries), file handling described below is available.[0005]
• Clicking “File” in the menu bar of an application which is already started opens a file menu. The file menu displays, in addition to items such as “New” and “Open”, a list of recently accessed files, and by specifying a file item in the list, it is possible to select with ease a file to be opened. The number of items to be displayed in the list of recently accessed files is set beforehand. Each time a file that is not on the list of recently accessed files is selected, it is added to the list, and when the number of files added becomes greater than the set number of items, the oldest item is removed from the list so that only the latest file items may always be displayed.[0006]
• Also, right-clicking the mouse with a file selected in a file browser or with an icon on the desktop selected opens a menu including the item “Open”. By selecting the item “Open”, it is possible to start the selected application or to open the selected file with its associated application started.[0007]
• If the item “Open” is selected in the file menu which has been opened by clicking “File” in the menu bar, a file selection screen is displayed. The file selection screen displays, in the case, the contents of the last accessed folder (i.e., directory). If a target file exists in the current folder, it can be opened by specifying the corresponding file item and then double-clicking the item or pressing the “Open” button. If the target file does not exist in the current folder, a “Select Folder (Select Directory)” button is pressed and a folder including the target file is selected in a folder selection screen to switch to that folder, so that the target file can be selected.[0008]
• Selecting the item “Open” in the file menu which has been opened by clicking “File” in the menu bar displays the file selection screen, and this file selection screen shows the contents of the last accessed folder, as mentioned above. If, in this case, a target file does not exist in the current folder, a “Browse” button is pressed to display a folder tree screen, and a folder including the target file is selected in the screen to switch to that folder, so that the target file can be selected.[0009]
• Further, a file selected in the file browser may be dragged and dropped onto an application which is already started, an icon of an application or folder on the desktop, or an icon of an application file or folder displayed in the file browser, all visibly shown on the screen. By dropping the selected file onto an icon of an application, it is possible to start the application and open the dragged file. Also, dropping the selected file onto an icon representing a folder permits the dragged file to be copied/moved to that folder.[0010]
• In cases where a target file is not on the list of recently accessed files in the file menu which has been opened by clicking “File” in the menu bar, however, the item “Open” is selected to display the file selection screen, and if the target file still does not exist in the current folder displayed in the file selection screen, double-clicking operation or the like usually needs to be performed a plurality of times in the folder selection screen, which is displayed in response to depression of the “Select Folder” button or the “Browse” button, to switch the current folder to a folder containing the target file before the target file is finally selected.[0011]
• Also, where a menu is opened with a file selected in the file browser or an icon on the desktop selected, selecting the item “Open” in the menu merely starts the application represented by the selected file or icon, or starts an application associated with the file represented by the selected file or icon and then opens the file. Accordingly, in the former case, a file needs to be opened after the application is started, and in the latter case, the file cannot be opened in an application that is not associated with the file.[0012]
• In the file menu which opens upon clicking “File” in the menu bar, the item “Open” is located at a position easiest to select in the menu. Since it is easier to select the item “Open” than the list of recently accessed files located at the bottom of the menu, in many cases the item “Open” is selected to open the file selection screen without the items in the list being checked. The file selection screen usually opens the last accessed folder, and therefore, if a target file exists in another folder, it is necessary that the current folder be switched to the folder containing the target file.[0013]
• Also, in the drag-and-drop operation, the dragged file can be dropped only onto an application which is already started, an icon of an application or folder on the desktop, or an icon of an application file or folder displayed in the file browser, all visibly shown on the screen, regardless of the position from which the file is dragged. In general, applications and folders which a user frequently uses are presumably limited in number. However, in cases where the target of drop operation is an application which is already started or an icon of an application file or folder displayed in the file browser, the application needs to be started beforehand, and where the target of drop operation is an icon of an application or folder on the desktop, such an icon needs to be placed on the desktop beforehand. Icons on the desktop remain displayed even after the drop operation is completed and thus the icons are unnecessary any longer; therefore, if the number of icons displayed increases, the desktop is crowded with icons and it is also difficult to find a target icon when a dragged file is to be dropped, lowering the operation efficiency. Further, in cases where the target of drop operation is distant from the position from which a file is dragged, the file needs to be dragged over a long distance to the position of the target of drop operation, hindering efficient drop operation. If the target of drop operation is hidden behind another window, moreover, a problem arises in that the drop operation cannot be performed.[0014]
SUMMARY OF THE INVENTION

DESCRIPTION OF THE PREFERRED EMBODIMENTS
• The present invention will be outlined first with reference to the drawings.[0049]
• FIG. 1 shows a theoretical configuration according to the present invention. In FIG. 1, a file handling device according to the present invention comprises environment setting means[0050]1 permitting the user to set display items, display conditions, etc.,settings storing means2 for storing the contents of settings set by means of the environment setting means1, history storing means3 for storing a history of opened files/folders, file menu item creation/display means4 functioning in relation to a file menu which is manipulated for selecting a file in an application, file selection screen item creation/display means5 functioning in relation to a file selection screen which is displayed when an item “Open” is selected in the file menu, folder tree item creation/display means6 functioning in relation to a folder tree menu which is displayed when a “Browse” button is pressed in the file selection screen, drop list window creation/display means7 for displaying a list of targets of drop operation during a drag operation, and file/icon menu item creation/display means8 functioning in relation to a menu which opens in a situation where a file/folder is selected in a file browser or an icon on desktop is selected.
• The environment setting means[0051]1 is used to set items displayed as menu items in menus to be displayed, such as the file menu, the file selection screen, the folder tree menu, the drop list window and the file/icon menu, display conditions at drag-and-drop operation, etc., and the settings are made by the user. The contents of the settings by means of the environment setting means1 are stored in thesettings storing means2, and are read out as needed by the file menu item creation/display means4, the file selection screen item creation/display means5, the folder tree item creation/display means6, the drop list window creation/display means7 or the file/icon menu item creation/display means8. The history storing means3 stores the history of opened files/folders in accordance with conditions set in thesettings storing means2 in relation to the numbers of display items.
• When the file menu is displayed in an application, the file menu item creation/display means[0052]4 acquires items of recently accessed files/folders from the history storing means3 and items of prespecified files/folders from thesettings storing means2, and adds the acquired items to the file menu to be displayed. The added items each serve as an object of selection, whereby manipulation on the file selection screen can be omitted or the number of manipulations required until a target file is selected can be reduced, thus improving the operation efficiency during the selection of a file. When the file selection screen is opened as a result of the selection of the item “Open” in the file menu of an application, the file selection screen item creation/display means5 acquires the items of recently accessed files/folders from the history storing means3 and the items of the prespecified files/folders from thesettings storing means2, and adds the acquired items to the file selection screen to be displayed. When the file selection screen is to be opened as a result of the selection of a folder item added in the file menu of an application by the file menu item creation/display means4, the file selection screen opens with its current folder switched to the selected folder. By selecting an added item, it is possible to reduce the number of manipulations required until a target file is selected and also the number of times the current folder is switched, whereby the efficiency of manipulation on the file selection screen and the efficiency in selecting a file can be improved. When the folder tree menu opens in response to depression of the “Browse” button in the file selection screen, the folder tree item creation/display means6 acquires the items of recently accessed files/folders from the history storing means3 and the items of the prespecified files/folders from thesettings storing means2, and adds the acquired items to the folder tree menu to be displayed. This improves the efficiency of manipulation on the folder tree menu as well as the efficiency in file selection. When a drag operation is started with a file/folder selected in a file browser, the drop list window creation/display means7 acquires the items of recently accessed files/folders from the history storing means3 and the items of the prespecified files/folders from thesettings storing means2, and displays the acquired items in the drop list window as target files/folders of drop operation onto which the selected file/folder may be dropped. Thus, after the start of a drag operation, the drop list window showing items onto which the selected file/folder may be dropped is displayed, whereby the efficiency of the drag-and-drop operation is improved. When a menu is displayed in a situation where a file/folder is selected in the file browser or an icon on the desktop is selected, the file/icon menu item creation/display means8 acquires the items of recently accessed files/folders from the history storing means3 and the items of the prespecified files/folders from thesettings storing means2, and additionally displays the acquired items in the menu which opens in the situation where a file/folder is selected in the file browser or an icon on the desktop is selected. By selecting an added folder item, it is possible to improve the efficiency in copying/moving a selected folder to one of the recently accessed folders and the prespecified folders, the efficiency in opening a recently accessed file or a prespecified file with a selected application file started, and the efficiency in opening a selected file with a prespecified application started.
• An embodiment of the present invention will be now described on the assumption that the invention is applied to Windows as an operating system based on a GUI environment, by way of example.[0053]
• FIG. 2 shows an example of configuration of a computer system which functions as the file handling device. The computer system comprises a central processing unit (CPU)[0054]11, amemory12, afloppy disk drive13, a CD-ROM (Compact Disk Read Only Memory) drive14, ahard disk drive15, akeyboard16, amouse17, and adisplay device18. The central processing unit11, thememory12, thefloppy disk drive13, the CD-ROM drive14, thehard disk drive15, thekeyboard16, themouse17 and thedisplay device18 are interconnected by asystem bus19.
• The[0055]hard disk drive15 stores an operating system, application programs, and a file handling program according to which the computer system functions as the file handling device. The file handling program is read out from thehard disk drive15, loaded in thememory12, and executed by the central processing unit11.
• The system configuration of the file handling device will be now described.[0056]
• FIG. 3 shows the system configuration of the file handling device. In the figure, elements enclosed by a rectangle represent logical devices each comprising a program having no screen, elements enclosed by a double line represent logical devices each comprising a program having a screen on which the user manipulates, and elements indicated by a cylindrical sign represent storage devices including a physical area, such as the[0057]hard disk drive15 or thememory12. A settingscreen control section21 constitutes a screen for the setting of a variety of items for operating the file handling device and permits the setting of items (files, folders) to be displayed and the display setting for the drop list window. The settingscreen control section21 is connected to asettings storing section22, and the contents of the settings by means of the settingscreen control section21 are stored in thesettings storing section22. At the time of setting, the contents of the settings previously stored in thesettings storing section22 are read out and reflected in the screen. Thesettings storing section22 stores format data for items to be displayed, data on files/folders, and format data for the list window, all set by means of the settingscreen control section21.
• The[0058]settings storing section22 is connected to ahistory storing section23. Thehistory storing section23 is provided to store a history of recently used files and folders, and stores data on recently accessed files and folders corresponding in number to the set display items stored in thesettings storing section22. If the number of display items are exceeded because a newly accessed file/folder does not coincide with any of the recently accessed file/folder items stored in thehistory storing section23, the oldest history data is removed while the newly accessed file/folder item is added, and the updated history is stored in thehistory storing section23.
• A file menu[0059]item creating section24 receives necessary data from thesettings storing section22 and thehistory storing section23 when the file menu is to be displayed and manipulated, and the output thereof is connected to a filemenu control section25. The filemenu control section25 includes, as menu items, at least added folder items, an item “Open”, and added file items. The added folder items and the item “Open” are associated with a file selection screenitem creating section26 such that when any one of these items is selected, thesection26 is called. When any one of the added file items is selected, no special process is executed and the corresponding file is opened.
• The file selection screen[0060]item creating section26 receives necessary data from thesettings storing section22 and thehistory storing section23 when called by the filemenu control section25, and the output thereof is connected to a file selectionscreen control section27. The file selectionscreen control section27 includes a “Browse” button. The “Browse” button is associated so as to call a folder treeitem creating section28. When an operation other than the depression of the “Browse” button is performed, a file is opened.
• The folder tree[0061]item creating section28 receives necessary data from thesettings storing section22 and thehistory storing section23 when called by the file selectionscreen control section27, and the output thereof is connected to a folder treescreen control section29. When a file is finally selected at the folder treescreen control section29, it is opened.
• A drop list window display[0062]item creating section30 receives necessary data from thesettings storing section22 and thehistory storing section23 when a drag operation is started on the desktop or on the file browser, and the output thereof is connected via a drop list window displayposition calculating section31 to a drop listwindow control section32. The drop listwindow control section32 includes application file items and folder items. When a dragged file is dropped onto an application file item, an application represented by the application file item is started and the dragged file is opened. When a dragged file is dropped onto a folder item, the dragged file is copied/moved to a folder represented by the folder item.
• When the file/icon menu is to be opened in a situation where a file/folder is selected in the file browser or an icon on the desktop is selected, a file/icon menu[0063]item creating section33 receives necessary data from thesettings storing section22 and thehistory storing section23, and the output thereof is connected to a file/iconmenu control section34. The file/iconmenu control section34 includes added file items and added folder items. If an added file item is specified, the corresponding file is opened with its associated application started, and if an added folder item is selected, the file is copied/moved to the selected folder.
• Examples of how screens are constructed by the respective control sections will be now described in order.[0064]
• FIGS.[0065]4(A) and4(B) show screens displayed by the setting screen control section, wherein FIG. 4(A) shows a menu bar and FIG. 4(B) shows a display item setting screen. As shown in FIG. 4(A), an application is provided with amenu bar41 for performing various operations, and left-clicking an item “Others” shown in themenu bar41 displays amenu42 near the clicked position. If an item “Settings” is selected in themenu42, asetting screen43 shown in FIG. 4(B) is displayed. Thesetting screen43 is provided with a displayitem setting screen44 and a drag-and-drop setting screen45.
• The display[0066]item setting screen44 is provided, for each of the file menu, the folder tree and the drop list window, with an entry field for the display/non-display switching of the file menu, the folder tree or the drop list window (entry field for specifying whether to display or not the corresponding one of the file menu, the folder tree and the drop list window), entry fields for the display/non-display switching of recently accessed files/folders and files/folders set by the user, and entry fields for the numbers of display items for specifying how many recently accessed files/folders and set files/folders are to be displayed. Below “Specify files to be displayed:” is located an entry screen for adding file names to be set, and below “Specify folders to be displayed:” is located an entry screen for adding folder names to be set. These entry screens are also provided with buttons for setting the order of priority of the items.
• Thus, the display[0067]item setting screen44 permits the user to customize the display/non-display setting of individual items, the setting of the numbers of items to be displayed, and the setting of the order of priority of items in accordance with the environment and usage of the user.
• Clicking the “Drag & Drop Settings” tab in the setting screen switches the screen to the drag-and-[0068]drop setting screen45.
• FIG. 5 shows the drag-and-drop setting screen displayed by the setting screen control section. The drag-and-[0069]drop setting screen45 is a screen which permits the user to set conditions for displaying the list window at the time of drag-and-drop operation, and is provided with screens for setting the display format, display position and display conditions for the list window.
• “List Window Display Format” allows the user to specify whether icons or file names are to be shown as display formats when the drop list window is displayed, whether the icons/file names are to be arranged in tabular form or not, and if the icons/file names are to be arranged in tabular form, whether the icons/file names are to be arranged vertically or horizontally.[0070]
• In “List Window Display Position”, the user can specify whether the drop list window is to be displayed in the moving direction of the mouse cursor, above, below, to the left or to the right of the mouse cursor position, and also can specify by the number of pixels how far the drop list window is to be displayed from the mouse cursor position.[0071]
• “Display Conditions” permits the user to set, by the distance of movement or by time, conditions for causing the drop list window to appear and disappear from the start of drag operation. Distance can be set by the number of pixels and time can be set in seconds.[0072]
• Thus, the user can customize the drop list window to be displayed in accordance with the environment and usage, and also can set the drop list window so that the displayed window may automatically disappear in case no drop operation is actually performed.[0073]
• The display items and the display conditions set in the display[0074]item setting screen44 and the drag-and-drop setting screen45 are stored in thesettings storing section22. The numbers of display items set in the displayitem setting screen44 define the numbers of files and folders to be kept in history in thehistory storing section23.
• The file[0075]menu control section25 has a screen described below, for example.
• FIG. 6 shows a screen displayed by the file menu control section. Clicking “File” on the[0076]menu bar41 of an application displays afile menu51. In this case, thefile menu51 additionally displays alist52 of recently accessed folders, alist53 of folders prespecified by the settings, and alist54 of files prespecified by the settings, all created by the file menuitem creating section24. The illustrated example of thefile menu51 shows a case where the displayitem setting screen44 in FIG. 4 has been set such that all file/folder items are to be displayed. Where any of the items are set so as not to be displayed, the file menu shows files/folders according to such settings.
• The[0077]list52 of recently accessed folders in thefile menu51 shows a list of folders recently accessed by the application concerned, thelist53 of prespecified folders shows a list of the folders set by the user, and thelist54 of prespecified files shows a list of the files set by the user.
• Thus, when the[0078]file menu51 is opened, recently accessed files/folders and the files/folders set by the user are displayed in the form of list, whereby files/folders which are used frequently can be selected with high efficiency.
• By selecting a file prespecified by the settings or a recently accessed file, it is possible to open the file. When a recently accessed folder or a folder prespecified by the settings is selected, the file selection screen opens. The file selection screen displayed in this case is the same as that which opens when the item “Open” is selected in the[0079]file menu51, but the current folder then displayed is the selected folder which was recently accessed or prespecified by the settings. It is therefore unnecessary to switch the current folder to a folder containing a target file, unlike the case where the item “Open” is simply selected.
• When the item “Open”, a recently accessed folder or a folder prespecified by the settings is selected in the[0080]file menu51, the file selection screen opens, and an example of the file selection screen will be now described.
• FIGS.[0081]7(A) and7(B) show screens displayed by the file selection screen control section, wherein FIG. 7(A) illustrates a case where recently accessed files are displayed and FIG. 7(B) illustrates a case where all items are displayed. Afile selection screen61 shown in FIG. 7(A) is the screen which is displayed when settings have been made in the displayitem setting screen44 of thesetting screen43 such that only recently accessed files should be displayed. Thisfile selection screen61 includes a “Location of file:” field showing a current folder, a list box showing a list of files contained in the folder, a “File name:” field in which the name of a file to be opened is entered, a “Files of type:” field for specifying the type of files to be listed in the list box, and also a “Recently accessed files:”list box62 located at the bottom of the screen and showing recently accessed files which have been set to be displayed in the displayitem setting screen44.
• The “Recently accessed files:”[0082]list box62 is created by the file selection screenitem creating section26 and is additionally displayed in thefile selection screen61.
• In cases where settings have been made in the display[0083]item setting screen44 such that recently accessed files, the files prespecified by the settings, recently accessed folders and the folders prespecified by the settings should be displayed, correspondinglist boxes64,65,66 and67 are additionally shown in afile selection screen63 as shown in FIG. 7(B).
• When a file listed in the[0084]list box64 or65 is selected, the name thereof appears in the “File name:” field, and the file can be opened by pressing the “Open” button. When a folder listed in thelist box66 or67 is selected, on the other hand, the current folder displayed in thefile selection screen63 is switched to the selected folder with the selected folder name shown in the “Location of file:” field, and a list of files contained in this folder is shown in thelist box68. By selecting a file in thelist box68 and pressing the “Open” button, it is possible to open the file.
• Thus, when the[0085]file selection screen63 opens, it shows a list of recently accessed files and the files set by the user, and accordingly, frequently used files can be selected with high efficiency. Even in the case where a target file does not exist in the folder displayed by thefile selection screen63, folders can be easily switched because a list of recently accessed folders and the folders set by the user, which are frequently used, is displayed.
• FIG. 8 shows another screen displayed by the file selection screen control section. A[0086]file selection screen71 which is displayed when the item “Open” is selected in the file menu includes a “Location of file:” field showing a current folder, a list box showing a list of files contained in the folder, a “File name:” field in which the name of a file to be opened is entered, a “Files of type:” field for specifying the type of files to be listed in the list box, an “Open” button for opening a file of which the name has been entered in the “File name:” field, and a “Cancel” button. Thefile selection screen71 additionally includes an “Open +Add File”button72, an “Open +Add Folder”button73, and an “Open +Add File & Folder”button74.
• Usually, a file of which the name has been entered in the “File name:” field can be opened by pressing the “Open” button. In this case, the “Open +Add File”[0087]button72 may be pressed instead of the “Open” button, whereupon the file is opened with data on the file added to the list of recently accessed files in thehistory storing section23. Pressing the “Open +Add Folder”button73 opens the file with data on the folder added to the list of recently accessed folders in thehistory storing section23, and pressing the “Open +Add File & Folder”button74 opens the file with data on the file and folder added to the respective lists of recently accessed files and folders stored in thehistory storing section23. In this manner, when a selected file is opened, data thereon can be positively added to the applicable list of thehistory storing section23 as recently accessed file/folder data. This is useful because the user very often makes a decision whether a file is to be displayed in the file menu or not in the course of actual work, and the above buttons permit the user to specify files/folders that should be kept in history to be displayed when a file is opened.
• In the example shown in FIG. 8, when the “Open +Add File”[0088]button72, the “Open +Add Folder”button73 or the “Open +Add File & Folder”button74 is pressed, data on the file/folder is added to the list(s) of recently accessed files/folders in thehistory storing section23. Alternatively, the user may be allowed the option to selectively specify the list of recently accessed files/folders or the list of the files/folders prespecified by the settings.
• Some file selection screens include a “Browse” button to facilitate the locating of a target folder, and the following describes a folder tree screen displayed when the “Browse” button is pressed.[0089]
• FIGS.[0090]9(A) and9(B) illustrate the operation performed when the “Browse” button is pressed, wherein FIG. 9(A) shows a screen displayed by the file selection screen control section and FIG. 9(B) shows a screen displayed by the folder tree screen control section. As shown in FIG. 9(A), afile selection screen81 displayed when the item “Open” is selected in the file menu includes a “Browse”button82, in addition to the “Location of file:” field showing a current folder and the list box showing a list of files contained in the folder. When the “Browse”button82 is pressed, the folder treeitem creating section28 is started. The folder treeitem creating section28 creates folder tree items in accordance with the display conditions set in the displayitem setting screen44 of thesetting screen43, and the folder treescreen control section29 displays afolder tree screen83 as shown in FIG. 9(B). Thefolder tree screen83 displays, in addition to ordinary folder tree information, alist84 of recently accessed files, alist85 of files prespecified by the settings, alist86 of recently accessed folders, and alist87 of folders prespecified by the settings.
• By selecting from the folder tree screen[0091]83 a recently accessed file or a file prespecified by the settings, it is possible to directly open the file. When a recently accessed folder or a folder prespecified by the settings is selected in thefolder tree screen83, the current folder of thefile selection screen81 shown in FIG. 9(A) switches to the selected folder.
• Thus, when the[0092]folder tree screen83 opens, it shows the lists of recently accessed files/folders and the user-specified files/folders, and therefore, it is unnecessary to manipulate the folder tree a plurality of times until a folder containing a target file is located, permitting efficient selection of frequently used files/folders.
• A drop target list window which is displayed at the time of drag-and-drop operation will be now described. By selecting a file/folder displayed in a file browser such as “Explorer” or an icon on the desktop, then moving (dragging) the selected object to another file, folder or icon with the mouse button held down, and releasing the mouse button (dropping the selected object), it is possible to copy/move the file/folder or to open the file with the application started. In this case, a file, folder or icon onto which the selected object is to be dropped must be visible on the screen. A window is therefore created and displayed which lists the files (application files)/folders set by the user as well as recently accessed folders in icon/label format and which permits drop operation. An example of the window displayed on screen will be described below. Since a file/folder is dragged on the file browser in the same manner as in dragging an icon on the desktop, in the following a drag operation of a file/folder on the file browser will be explained.[0093]
• FIG. 10 shows a screen which is displayed by the drop list window control section at the time of drag operation. In FIG. 10 is shown a[0094]file browser91. Let it be assumed that the folder “images” is selected and drag operation is started with the file “MyImage.bmp” specified, then a droptarget list window92 is displayed as a foreground window in the vicinity of the position where the drag operation has been started. The droptarget list window92 is displayed in accordance with the display conditions set in the drag-and-drop setting screen45. If the drag-and-drop setting screen45 has been set as shown in FIG. 5, for example, the droptarget list window92 is displayed at a distance of 50 pixels in the moving direction of the mouse cursor and at a distance of one pixel from the mouser cursor, and shows icons as display objects in tabular form. When drag operation is started, displacements of the mouse in the X- and Y-axis directions are detected, and based on a position separated by the distance calculated from the magnitudes of the detected displacements, a position in the vicinity of the position where the drag operation has been started is determined. This calculation is performed by the drop list window displayposition calculating section31. The droptarget list window92 shows, for example, the icons of “Application File 1”, “Application File 2”, “Folder 1” and “Folder 2” prespecified by the settings, and the icons of “Folder 1” and “Folder 2” recently accessed. These icons are prepared by the drop list window displayitem creating section30.
• By continuously dragging a file and then dropping it onto an icon of an application prespecified by the settings, it is possible to open the dragged file in the application represented by the icon onto which the file has been dropped. Where the icon onto which the file is dropped is a folder prespecified by the settings or a recently accessed folder, the dragged file can be copied/moved to the folder represented by the icon onto which the file has been dropped. Whether a copy or move operation is performed is governed by general manipulations defined in the environment concerned. For example, if a file is dropped with the “Ctrl” key held down, the file is copied, and if a file is dropped without the “Ctrl” key being depressed, the file is moved.[0095]
• The items displayed in the drop[0096]target list window92 are switched depending on the object to be dragged. Specifically, if the dragged object is a single or a plurality of data files, applications and folders are selected as display items to be listed. On the other hand, if the dragged object is a single or a plurality of application files, a combination of an application file and a data file, or a combination of a single or a plurality of folders and a single or a plurality of files, folders are selected as display items to be listed. In the example shown in FIG. 10, applications and folders are displayed in the droptarget list window92 because the dragged object is a data file containing a bit-mapped image.
• Thus, at the time of drag operation, the drop[0097]target list window92 showing the lists of the user-specified files (application files)/folders and recently accessed folders in icon/label format and permitting drop operation is displayed as a foreground window at an optimum position in the vicinity of the mouse cursor position. By dropping the dragged file onto an item representing an application, it is possible to start the application represented by the item and then open the file therein, and by dropping the dragged file onto an item representing a folder, it is possible to copy/move the file to the folder. Accordingly, drag-and-drop operation can always be performed with a minimum number of manipulations regardless of the position where the drag operation has been started, whereby the efficiency of drag-and-drop operation is improved. Since it is unnecessary to place application/folder icons that the user desires to use in advance on the desktop, it is possible to minimize the number of icons displayed uselessly and thus to prevent the desktop from being crowded with icons. Further, a list of suggested drop targets registered beforehand is displayed in advance of drop operation as a foreground window, and this permits drop operation to be performed even when many windows are displayed on the screen.
• A menu which opens in a situation where a file/folder is selected in the file browser or an icon on the desktop is selected will be now described. The menu which opens while a file/folder is selected in the file browser is the same as that which opens while an icon on the desktop is selected, and therefore, in the following description, the former menu will be taken as an example.[0098]
• FIG. 11 shows a first screen displayed by the file/icon menu control section. In FIG. 11, a[0099]file browser101 is shown, and with a “Program Files” folder selected, “MyApplication.exe”, which is a single application file, is selected and then right-clicked or “MyApplication.exe” is directly right-clicked, whereupon amenu102 opens. Thismenu102 additionally displays an “Open Recently Accessed File”list103 and an “Open Prespecified File”list104, both created by the file/icon menuitem creating section33. The added menu items are also shown in the menu which appears when an icon of a single application file on the desktop or in the browser or a shortcut icon on the desktop is selected and right-clicked.
• By selecting a recently accessed file or prespecified file from the[0100]menu102, it is possible to open the file in the previously selected application. Thus, unlike the conventional menu which merely starts the application when the item “Open” is selected therein, themenu102 permits an operation such that when a file is selected therein, the selected file is automatically opened with the application started. Since recently used files and the files prespecified by the user are shown in the “Open Recently Accessed File”list103 and the “Open Prespecified File”list104, respectively, frequently used files can be quickly opened in the selected application. Thus, only a few operations are required to start the application and to open a desired file from the file browser, whereby the operation efficiency is improved.
• FIG. 12 shows a second screen displayed by the file/icon menu control section. In FIG. 12, the[0101]file browser101 is shown, and with an “images” folder selected, “MyImage1.bmp”, which is a data file, is selected and then right-clicked or “MyImage1.bmp” is directly right-clicked, whereupon amenu105 opens. Thismenu105 additionally displays an “Open in Prespecified Application”list106, a “Copy/Move to Recently Accessed Folder”list107 and a “Copy/Move to Prespecified Folder”list108, all created by the file/icon menuitem creating section33. The added menu items are also shown in the menu which appears when a single or a plurality of data files or icons thereof are selected and right-clicked on the desktop or in the browser.
• By selecting a prespecified application from the[0102]menu105, it is possible to start the application and open the previously selected data file. Thus, unlike the conventional menu which starts the only one application defined in Windows when the item “Open” is selected therein, themenu105 permits a selected file to be opened in a desired application, regardless of the Windows definitions, by setting a plurality of applications beforehand.
• Also, by selecting an item “Copy/Move to Recently Accessed Folder” or “Copy/Move to Prespecified Folder” in the[0103]menu105, it is possible to copy/move the selected data file to the folder represented by the selected item. Whether a copy or move operation is performed is governed by general manipulations defined in the environment.
• FIG. 13 shows a third screen displayed by the file/icon menu control section. In FIG. 13, the[0104]file browser101 is shown, and with the “images” folder selected, a folder “MyImageFolder” is selected and then right-clicked or the folder “MyImageFolder” is directly right-clicked, where upon amenu109 opens. Thismenu109 additionally displays the “Copy/Move to Recently Accessed Folder”list107 and the “Copy/Move to Prespecified Folder”list108, both created by the file/icon menuitem creating section33. The added menu items are also shown in the menu which appears when an icon representing a file or a folder or a plurality of application files, data files or folders are selected and right-clicked on the desktop or in the browser.
• By selecting an item “Copy/Move to Recently Accessed Folder” or “Copy/Move to Prespecified Folder” in the[0105]menu109, it is possible to copy/move the selected folder to the folder represented by the selected item. Thus, with a few operations in thefile browser101, a desired folder can be copied/moved to frequently used folders.
• The flows of processes executed by the item creating sections etc. mentioned above will be now described.[0106]
• FIG. 14 is a flowchart showing the flow of a file menu selection process. In the file menu selection process, when “File” is selected in an application, for example, file menu items are created by means of the file menu item creating section (Step S[0107]1). Creation of file menu items will be explained later. It is then determined whether or not the item “Open” has been selected in the file menu in which the created file menu items are additionally displayed (Step S2). If the item “Open” has been selected, a standard folder of the application concerned is set (Step S3), and the file selection screen is called with its current folder switched to the standard folder in a file selection screen process (Step S4). The file selection screen process will be described later. Subsequently, a file is selected in the file selection screen (Step S5), data on the selected file and the folder containing the selected file is output as history data to the history storing section (Step S6), and the selected file is opened in the application (Step S7).
• If it is judged in Step S[0108]2 that the item “Open” has not been selected, it is determined whether the item selected in the file menu is a recently accessed folder item or a folder item prespecified by the settings (Step S8, S9). If either folder item is selected in the file menu, the folder represented by the selected item is set (Step S10), and the file selection screen process is executed with the current folder switched to the set folder.
• If it is judged in Steps S[0109]8 and S9 that no folder item has been selected, it is determined whether or not a prespecified file item has been selected (Step S11). When a file item has been selected, a file represented by this menu item is selected (Step S12), and the flow proceeds to the step of storing data on the file in history.
• In cases where a menu item in the file menu other than the item “Open” and the items created and added by the file menu item creating section has been selected, a corresponding process is executed as in the conventional menu (Step S[0110]13).
• FIG. 15 is a flowchart showing the flow of the file menu item creation process. In the file menu item creation process, first, basic menu items originally possessed by the application concerned are created (Step S[0111]21), and the settings are read from the settings storing section (Step S22).
• Subsequently, the number of recently accessed folder items to be displayed is checked (Step S[0112]23); if the set number of display items is not “0”, n folder names are read from the history storing section and folder items are created (Step S24). If it is judged in Step S23 that the set number of display items is “0”, then the number of prespecified folder items to be displayed is checked (Step S25); if the set number of display items is not “0”, n folder names are read from the settings storing section and folder items are created (Step S26). If it is judged in Step S25 that the set number of display items is “0”, then the number of prespecified file items to be displayed is checked (Step S27); if the set number of display items is not “0”, n file names are read from the settings storing section and file items are created (Step S28). Subsequently, other basic menu items are created (Step S29).
• FIG. 16 is a flowchart showing the flow of the file selection screen process. First, in the file selection screen process, a file/folder item creation process is executed (Step S[0113]31). The file/folder item creation process will be explained later. Subsequently, it is determined whether the selected item is a recently accessed folder item or a folder item prespecified by the settings (Step S32, S33). When the selected item is a folder item, a folder represented by the selected item is set and the current folder of the currently open file selection screen is switched to the set folder (Step S34), whereupon the flow returns to Step S32.
• Where the file selection screen has the “Browse” button, it is then determined whether or not the “Browse” button has been pressed (Step S[0114]35). If the “Browse” button has been pressed, a folder tree screen process is executed (Step S36), and if an item is selected in the folder tree screen, the file selection screen is closed (Step S37). The folder tree screen process will be described later.
• Subsequently, it is determined whether or not a file item prespecified by the settings has been selected (Step S[0115]38), and if a prespecified file item has been selected, a file represented by the selected file item is selected (Step S39), and the flow proceeds to Step S37 to close the file selection screen. If other originally existing items or some other items are selected, corresponding selection processes are executed (Step S40).
• FIG. 17 is a flowchart showing the flow of the file/folder item creation process. In the file/folder item creation process, first, the settings are read from the settings storing section (Step S[0116]41). Then, the number of recently accessed folder items to be displayed is checked (Step S42), and if the set number of display items is not “0”, n folder names are read from the history storing section and folder items are created (Step S43). If it is judged in Step S42 that the set number of display items is “0”, then the number of prespecified folder items to be displayed is checked (Step S44), and if the set number of display items is not “0”, n folder names are read from the settings storing section and folder items are created (Step S45). If it is judged in Step S44 that the set number of display items is “0”, then the number of prespecified file items to be displayed is checked (Step S46), and if the set number of display items is not “0”, n file names are read from the settings storing section and file items are created (Step S47).
• FIG. 18 is a flowchart showing the flow of the folder tree screen process. In the folder tree screen process, first, the file/folder item creation process shown in FIG. 17 is executed (Step S[0117]51). Subsequently, it is determined whether the selected item is a recently accessed folder item or a folder item prespecified by the settings (Step S52, S53). When the selected item is a folder item, a folder represented by the selected item is set and is opened in the displayed tree (Step S54), whereupon the flow returns to Step S52.
• Subsequently, it is determined whether or not a prespecified file item has been selected (Step S[0118]55); if a prespecified file item has been selected, the corresponding file is selected (Step S56) and the screen is closed (Step S57). If the selected item is not a prespecified file item, a corresponding selection process of the folder tree screen is carried out (Step S58).
• FIG. 19 is a flowchart showing the flow of a list window process executed at the time of drag operation. The list window process for drag operation is initiated in response to start of a drag operation. When a drag operation is started, various settings are read from the settings storing section (Step S[0119]61) and the cursor position at the start of the drag operation is stored (Step S62).
• Subsequently, it is determined whether or not the list window is displayed (Step S[0120]63), and if the list window is not displayed, then it is determined whether or not the conditions for displaying the list window are fulfilled (Step S64). If the display conditions are fulfilled, a list window is created (Step S65), the position of the list window is calculated (Step S66), and the created list window is displayed at the calculated position as a foreground window (Step S67). The list window creation process and the list window position calculation process will be described in detail later. If the display conditions are not fulfilled, the flow proceeds to an ordinary drop process.
• If it is judged in Step S[0121]63 that the list window is displayed, it is determined whether or not a drop operation has been performed on the list window (Step S68), and if a drop operation has been performed on the list window, a list window drop process is executed (Step S69). The list window drop process will be described later.
• Then, it is determined whether or not the conditions for closing the list window are fulfilled (Step S[0122]70). If the list window closing conditions are fulfilled, the list window is closed (Step S71). A standard drop process is thereafter carried out (Step S72), and it is then determined whether or not the drag process has ended (Step S73). If the drag process has not ended yet, the flow returns to Step S63, and if the drag process has ended, this process is terminated.
• FIG. 20 is a flowchart showing the flow of the list window creation process. In the list window creation process, first, a basic window is created (Step S[0123]81), and the settings such as display position, display format, etc. are read from the settings storing section (Step S82).
• It is then determined whether or not the dragged object is a data file (Step S[0124]83), and if the dragged object is a data file, the number of prespecified file items to be displayed is checked (Step S84). If the set number of display items is not “0”, n application file names are read from the settings storing section and file items are created (Step S85). Subsequently, the number of recently accessed folder items to be displayed is checked (Step S86); if the set number of display items is not “0”, n folder names are read from the history storing section and folder items are created (Step S87). Then, the number of prespecified folder items to be displayed is checked (Step S88); if the set number of display items is not “0”, n folder names are read from the settings storing section and folder items are created (Step S89).
• FIG. 21 is a flowchart showing the flow of the list window position calculation process. First, in the list window position calculation process, the mouse cursor position at the start of the drag operation is acquired (Step S[0125]91). Then, the list window display conditions are read from the settings storing section (Step S92), and the cursor position at the current point of time is acquired (Step S93). Based on the acquired cursor positions at the start of the drag operation and at the current point of time, the moving direction of the cursor is calculated (Step S94). Subsequently, the position where the list window is to be displayed is calculated based on the position and moving direction of the cursor (Step S95).
• FIG. 22 is a flowchart showing the flow of the list window drop process. First, in the list window drop process, when the dragged file/folder is dropped onto an object in the list window, a determination is made as to whether or not the target object of drop operation is a recently accessed folder item, and then whether or not the target object of drop operation is a folder item prespecified by the settings (Step S[0126]101, S102). When either folder item is the target object of drop operation, it is determined whether or not the “CTRL” key had been depressed during the drop operation (Step S103). If the “CTRL” key had been pressed during the drop operation, the dragged file/folder is copied to the folder represented by the item onto which the file/folder was dropped (Step S104), and if not, the dragged file/folder is moved to the folder represented by the item onto which the file/folder was dropped (Step S105). If the item onto which the dragged file/folder has been dropped is not a folder item, it is determined whether or not the item in question is an application item (Step S106). If the item is not an application item, the flow returns to Step S101; if the item is an application item, on the other hand, the application represented by the item onto which the dragged file has been dropped is started (Step S107) and the dragged file is opened (Step S108).
• A menu selection process for a file in the file browser or an icon on the desktop will be now described.[0127]
• FIG. 23 is a flowchart showing the flow of the file/icon menu selection process. In the menu selection process for a file in the file browser or an icon on the desktop, first, when a menu is to be opened in response to a right-click etc., a process for creating file/icon menu items is executed (Step S[0128]111). The file/icon menu item creation process will be described in detail later.
• Subsequently, it is determined whether an item selected in the displayed menu is a recently accessed folder item or a folder item prespecified by the settings (Step S[0129]112, S113). When either folder item has been selected, it is determined whether or not the “CTRL” key had then been depressed (Step S114). If the “CTRL” key had been depressed during the menu selection, the file/folder selected in advance of the opening of the menu is copied to the folder specified by the menu selection (Step S115), and if not, the previously selected file/folder is moved to the folder specified by the menu selection (Step S116).
• It is then determined whether or not the menu selection designates a file item prespecified by the settings (Step S[0130]117), and if the selected item is not a file item prespecified by the settings, other menu item processes are executed (Step S118). If it is judged in Step S117 that a file item prespecified by the settings has been selected in the menu, it is determined whether or not the file selected in the menu is a data file (Step S119). If the file item selected in the menu represents a data file, the application represented by the file/icon selected in advance is started (Step S120) and the data file represented by the menu item selected in the menu is opened (Step S121). If, on the other hand, it is judged in Step S119 that the file item selected in the menu is not a data file, that is, the selected file item is an application file, the application represented by the file item selected in the menu is started (Step S122) and the data file represented by the file/icon selected in advance is opened (Step S123).
• FIGS. 24 and 25 show the flow of the file/icon menu item creation process. When a file/folder in the file browser or an icon on the desktop is right-clicked, first, basic items are created (Step S[0131]131) and the settings are read from the settings storing section (Step S132). It is then determined whether or not the selected file/icon is a single application (Step S133). If the file/icon on which the menu has been opened is an application, the number of recently accessed file items to be displayed is checked (Step S134); if the set number of display items is not “0”, n file names are read from the history storing section and file items are created (Step S135). Subsequently, the number of prespecified file items to be displayed is checked (Step S136); if the set number of display items is not “0”, n file names are read from the settings storing section and file items are created (Step S137). The other remaining items of the menu are then created (Step S138).
• If it is judged in Step S[0132]133 that the selected file/icon is not a single application, it is determined whether or not the selected file/icon is a data file (Step S139). If the selected file/icon is a data file, the number of prespecified file items to be displayed is checked (Step S140); if the set number of display items is not “0”, n application file names are read from the settings storing section and file items are created (Step S141). Subsequently, the number of recently accessed folder items to be displayed is checked (Step S142); if the set number of display items is not “0”, n folder names are read from the history storing section and folder items are created (Step S143). Then; the number of prespecified folder items to be displayed is checked (Step S144); if the set number of display items is not “0”, n folder names are read from the settings storing section and folder items are created (Step S145). Finally, the other remaining items of the menu are created (Step S146).
• The contents of the above-described processes achieved by the function of the computer may be described in a program to be recorded on a computer-readable recording medium. The program is executed by the computer, whereupon the above processes are achieved by the computer. The computer-readable recording medium includes a magnetic storage device and a semiconductor memory. In order to bring the program to market, the program may be stored in portable recording media, such as CD-ROMs or floppy disks, to be distributed, or the program may be stored in a storage device of a computer connected to a network so that it can be transferred to other computers through the network. The program is stored in a hard disk drive or the like of a computer, and when it is to be executed by the computer, the program is loaded in the main memory and executed.[0133]
• As described above, according to the present invention, preset numbers of preset menu items are additionally displayed in the file menu, the file selection screen and the folder tree screen, which open from within applications, as well as in the menu which opens in relation to a file/folder or an icon thereof displayed in the file browser or on the desktop, and also preset numbers of preset items as target objects of drop operation are displayed as a window during drag-and-drop operation. This permits frequently used files/folders to be added to the menus in advance, making it possible to eliminate multiple selections required until a target file is opened or to greatly reduce the number of selections. At the time of drag-and-drop operation, the drop target list window in which frequently used files/folders are listed and which permits drop operation is displayed as a foreground window in the vicinity of the mouse cursor after the drag operation is started, and this eliminates the need to start an application in advance, to move a target object of drop operation to a position permitting drop operation, or to display a target object of drop operation such that drop operation can be performed, thus improving the efficiency of drag-and-drop operation. Further, since the items to be additionally displayed in the menus etc. and their display conditions can be set, the menus can be freely customized in accordance with user environments.[0134]
• The foregoing is considered as illustrative only of the principles of the present invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and applications shown and described, and accordingly, all suitable modifications and equivalents may be regarded as falling within the scope of the invention in the appended claims and their equivalents[0135]
