Fig. 1 is a flowchart of a method for tracing a file according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step S102, detecting a current active document window title and a current active window title, and archiving the current active document window title as a logical source document window title, wherein the current active window is a child window of the current active document window.
Optionally, the current active document window is, for example, a word window in an active state at the current moment, and the current active window is a child window of the word window, for example, a "new" window, "an" option "window," a "save as" window, and the like in the word window.
And establishing and starting the monitoring front active document window and the current active window, and extracting the current active document window title and the current active window title in real time.
Step S104, setting target mark information in a target process to which the logic source document window belongs in the case that the current active window title is detected as the target title.
According to other alternative embodiments of the present application, in the case where the current active window is detected as being entitled "save as" or "save file", the target flag information is set in the target process to which the logical source document window belongs.
The tag information of the "save as" operation is the file name and file format used when saving the file. Such information may assist the user in identifying and locating saved files, as well as determining the type and storage location of the files. In performing the "save as" operation, the user may select the name of the file and the saved directory, and may select the format of the file, such as a text file (.txt), a Word document (.docx), a PDF file (.pdf), and the like. The tag information may also include attributes of the creation date, modification date, and file size of the file.
Step S106, in the case that the current active window title is detected not to be the target title, and in the case that the target mark information exists in the target process, determining whether the logical source document window title is the same as the current active document window title.
If it is detected that the current active window title is not "save as" or "save file", it is determined whether the target mark information set in step S104 exists in the target process, and if the target mark information exists in the target process, it is determined whether the logical source document window title is the same as the current active document window title.
Step S108, under the condition that the title of the logic source document window is different from the title of the current active window, determining the traceability relationship between the source file corresponding to the logic source document window and the target file corresponding to the current active document window according to the file handle table in the target process.
The file handle table is a data structure used in the operating system to manage open files, typically an array or linked list, with each element representing an open file. Each file handle contains metadata information of the file, such as file name, file type, file size, etc., and a read-write pointer of the file for recording the current read-write location of the file. The purpose of the file handle table is to track and manage all open files so that the operating system can quickly locate and access these files when needed. When an application opens a file, the operating system assigns a file handle and adds the file handle to the file handle table. When the application program reads and writes the file, the operating system can find the corresponding file according to the information in the file handle table and perform corresponding read and write operations. The file handle table is also used for realizing sharing and concurrent access of files. Multiple application programs can open the same file at the same time, each application program can have a file handle, and the file handles can be managed through a file handle table, so that concurrent access of the files is ensured not to conflict.
According to the steps, when the first window title is detected to be the target title, target mark information corresponding to the target operation is set in the target process to which the first window belongs, when the first window title is detected not to be the target title, and when the target mark information exists in the target process, whether the second window title corresponding to the first window title is the same as the second window title is determined, when the first window title is different from the second window title, the traceability relationship between the first file and the second file is determined according to the first window title and the second window title in the file handle table, and the aim of determining the traceability relationship between the file which is stored and the corresponding source file is achieved, so that the technical effect of accurately determining the position of the source file is achieved.
According to some optional embodiments of the application, detecting the current active document window title and the current active window title comprises: acquiring a first handle corresponding to a current active document window through a first preset function in a preset application program interface; acquiring the content of the current active document window title through the first handle; determining a first character set corresponding to the current active document window title according to the content of the current active document window title; detecting whether a first character set at a first moment is the same as a first character set at a second moment within a preset duration, wherein the first moment is the current moment, and the second moment is the previous moment which is a preset time interval with the first moment; acquiring a second handle corresponding to the current active window through a second preset function in a preset application program interface; acquiring the content of the current active window title through the second handle; determining a second character set corresponding to the current active window title according to the content of the current active window title; and detecting whether the second character set at the third moment is the same as the second character set at the fourth moment within the preset duration, wherein the third moment is the current moment, and the fourth moment is the previous moment which is a preset time interval with the first moment.
Alternatively, to obtain the current active document window title and the current active window title, the following steps may be used:
1. importing required libraries and modules:
```python
import win32gui
```
2. defining a callback function to enumerate all windows and find the title of the active window:
```python
def get_active_window_title():
active_window = win32gui.GetForegroundWindow()
window_title = win32gui.GetWindowText(active_window)
return window_title
```
3. invoking the function to obtain the title of the active window:
```python
title = get_active_window_title()
print(title)
```
according to other alternative embodiments of the present application, in the case where the logical source document window header is the same as the current active window header, the source file corresponding to the logical source document window is the same file as the destination file corresponding to the current active document window.
In some alternative embodiments of the present application, the target mark information in the target process is removed in the event that the logical source document window title is not the same as the current active window title.
Alternatively, one process may correspond to a plurality of already opened files. Each process has a file descriptor table in which information of the files that have been opened is stored. The file descriptor is a non-negative integer that uniquely identifies a file that has been opened. Through the file descriptor, the process can perform read-write operation on the opened file. Common file descriptors include standard input, standard output, and standard error output, with file descriptors being 0, 1, and 2, respectively. In addition, the process can also open other files through system call and obtain corresponding file descriptors. Thus, one process may correspond to multiple files that have been opened at the same time.
As some alternative embodiments of the present application, the target title is a title with target information, where the target information includes at least: information is stored.
Alternatively, the targets are entitled "save as", "save file", and the like.
In some alternative embodiments of the application, the file handle table includes: the method comprises the steps of associating a logical source document window title with a current active document window title, first path information of a source file corresponding to the logical source document window, and second path information of a target file corresponding to the current active document window.
