FIG. 1 is a flowchart of a preferred embodiment of a file search method disclosed in the present invention. Wherein, according to different requirements, the order of the steps in the flow chart can be changed, and some steps can be omitted.
S11、电子设备接收携带有文本关键词的文件查找请求。S11. The electronic device receives a file search request carrying text keywords.
本发明实施例中，当用户需要查找某个文件时，用户可以在应用层输入携带有文本关键词的文件查找请求。In the embodiment of the present invention, when a user needs to search for a certain file, the user may input a file search request carrying text keywords at the application layer.
其中，所述文本关键词可以为文件名称中的全部或部分关键词，或者，所述文本关键词可以为文件包括的文本内容中的部分关键词。Wherein, the text keywords may be all or part of the keywords in the file name, or, the text keywords may be part of the keywords in the text content included in the file.
作为一种可选的实施方式，步骤S11所述接收携带有文本关键词的文件查找请求之前，所述方法还包括：As an optional implementation manner, before receiving the file search request carrying text keywords in step S11, the method further includes:
读取当前文件系统中的所有文件；Read all files in the current file system;
针对每个所述文件，根据所述文件的文件后缀名、文件大小以及文件存储格式，判断所述文件是否为文本文件；For each of the files, determine whether the file is a text file according to the file suffix name, file size and file storage format of the file;
若所述文件为文本文件，基于所述文件的文件名以及文本内容，创建文本文件索引；If the file is a text file, based on the file name and text content of the file, create a text file index;
若所述文件为非文本文件，基于所述文件的文件名，创建非文本文件索引；If the file is a non-text file, based on the file name of the file, create a non-text file index;
根据所述文本文件索引以及所述非文本文件索引，创建所述本地文件索引。The local file index is created according to the text file index and the non-text file index.
在该可选的实施方式中，以NTFS(New Technology File System，新技术文件系统)为例，大部分windows都是这样的文件系统。NTFS里会维护一张表MTF(Master FileTable，主文件表)，所有的文件夹和文件名称都被存储在该MTF表中，在首次启动时就通过读取该MTF表的内容，获取到所有的文件名称和路径，进一步地，对该所有文件进行筛查，以区分哪些文件是文本文件，哪些文件是非文本文件，并创建本地文件索引。后续如果用户操作文件，可以对本地文件索引进行修改。In this optional implementation manner, NTFS (New Technology File System, new technology file system) is taken as an example, and most windows are such file systems. A table MTF (Master FileTable, master file table) is maintained in NTFS, and all folders and file names are stored in the MTF table, and all files are obtained by reading the contents of the MTF table when starting for the first time. Further, all files are screened to distinguish which files are text files and which files are non-text files, and create a local file index. If the user operates the file later, the local file index can be modified.
通常，文本文件的文件后缀名可以包括但不限于doc、txt、json，非文本文件的文件后缀名可以包括但不限于mp4、avi、mpg、mlv，文本文件所占内存比非文本文件所占内存要小，此外，为了避免恶意将庞大的非文本文件修改成文本文件，还需要对文本文件进行鉴别。Usually, the file suffixes of text files can include but not limited to doc, txt, json, the file suffixes of non-text files can include but not limited to mp4, avi, mpg, mlv, and the memory occupied by text files is higher than that of non-text files The memory should be small. In addition, in order to avoid maliciously modifying huge non-text files into text files, it is also necessary to identify the text files.
其中，每个不同类型的文件，在计算机上的存储会以不同的结构存在，这些各种有规律的结构被描述成文件存储格式，例如：Windows平台的exe，dll，sys文件统称为PE文件，并拥有自己特有的格式，比如文件的前两个字节为4D5A，这是PE文件的标志，再比如MP4格式的文件，第4-7字节的内容就是66 74 79 70。因此，在对文本文件进行鉴别时，还可以根据文件在计算机中的文件存储格式来进行判断，Among them, each different type of file will be stored in a different structure on the computer, and these various regular structures are described as a file storage format, for example: exe, dll, and sys files on the Windows platform are collectively called PE files , and has its own unique format. For example, the first two bytes of the file are 4D5A, which is the symbol of the PE file. For example, the file in MP4 format, the content of the 4th to 7th bytes is 66 74 79 70. Therefore, when identifying a text file, it can also be judged according to the file storage format of the file in the computer,
具体的，针对每个所述文件，可以根据所述文件的文件后缀名、文件大小以及文件存储格式，判断所述文件是否为文本文件，如果所述文件的文件后缀名属于文本文件的文件后缀名，且所述文件的文件大小不超过预设的文本文件大小(比如10M)，且所述文件的文件存储格式为文本文件的文件存储格式，则可以确定所述文件为文本文件，反之，如果所述文件的文件后缀名不属于文本文件的文件后缀名，或所述文件的文件大小超过预设的文本文件大小(比如10M)，或所述文件的文件存储格式为非文本文件的文件存储格式，只要上述三个条件中的任何一个或者任何两个或者三个成立，则可以确定所述文件为非文本文件。Specifically, for each of the files, it can be judged whether the file is a text file according to the file suffix name, file size and file storage format of the file, if the file suffix name of the file belongs to the file suffix of the text file name, and the file size of the file does not exceed the preset text file size (such as 10M), and the file storage format of the file is the file storage format of the text file, then it can be determined that the file is a text file, otherwise, If the file extension of the file does not belong to the file extension of the text file, or the file size of the file exceeds the preset text file size (such as 10M), or the file storage format of the file is a non-text file Storage format, as long as any one or any two or three of the above three conditions are satisfied, it can be determined that the file is a non-text file.
在区分文本文件和非文本文件后，针对文本文件，可以基于文件名以及文本内容，创建文本文件索引，针对非文本文件，可以基于文件名，创建非文本文件索引，进而根据所述文本文件索引以及所述非文本文件索引，创建本地文件索引。After distinguishing between text files and non-text files, for text files, a text file index can be created based on the file name and text content, and for non-text files, a non-text file index can be created based on the file name, and then according to the text file index As well as the non-text file index, a local file index is created.
基于上述方式创建的本地文件索引，当输入的文本关键词与文件名匹配时，可以将匹配的文本文件或非文本文件搜索出来，当输入的文本关键词与文本内容匹配时，可以将匹配的文本文件搜索出来。Based on the local file index created in the above way, when the input text keyword matches the file name, the matched text file or non-text file can be searched out; when the input text keyword matches the text content, the matched Text files are searched out.
S12、电子设备根据所述文本关键词，在基于文件系统过滤驱动的本地文件索引中进行搜索，获得目标文件。S12. The electronic device searches the local file index based on the filter driver of the file system according to the text keyword to obtain the target file.
本发明基于windows的文件系统过滤驱动MiniFilter对本地文件索引包括的文件的操作事件进行监听。在操作系统的底层插入一个MiniFilter模块，那么文件的创建、删除、修改以及查看操作成功前的动作消息会被该MiniFilter模块过滤，用户可以选择拦截或者放行，同时也可以获取到文件的全路径、名称、内容以及属性等信息。The present invention is based on the windows file system and drives the MiniFilter to monitor the operation events of the files included in the local file index. Insert a MiniFilter module at the bottom layer of the operating system, then the action messages before the file creation, deletion, modification, and viewing operations are successful will be filtered by the MiniFilter module, and the user can choose to intercept or release, and can also obtain the full path of the file, Information such as name, content, and attributes.
由于本地文件索引是基于文件系统过滤驱动的，无论之前的用户对文件做什么操作(创建、删除、修改)均可以被文件系统过滤驱动监听，进而修改本地文件索引，以实时更新本地文件索引。后续用户输入文本关键词进行查找时，电子设备就可以从文件名以及文本内容两个方面进行查找，以搜索出文件名与所述文本关键词匹配的目标文件，或者，搜索出文本内容与所述文本关键词匹配的目标文件。即，所述目标文件的文件名与所述文本关键词匹配，或，所述目标文件的文本内容与所述文本关键词匹配。Since the local file index is driven based on the file system filter, no matter what operations (create, delete, modify) the previous user does to the file, it can be monitored by the file system filter driver, and then the local file index can be modified to update the local file index in real time. When the user enters the text keyword to search, the electronic device can search from the two aspects of the file name and the text content, so as to search out the target file whose file name matches the text keyword, or search out the text content matching the text keyword. The target file matching the keyword in the above text. That is, the file name of the target file matches the text keyword, or the text content of the target file matches the text keyword.
本发明中，可以高效精准的查找文件系统中的所有相关文件，以最快的速度从驱动层(即文件系统过滤驱动)拿到最精准文件的信息，同时，支持多种方式查找文件，也可以通过文本内容进行快速定位，大大提高系统使用的效率。In the present invention, all related files in the file system can be searched efficiently and accurately, and the most accurate file information can be obtained from the driver layer (ie file system filter driver) at the fastest speed. Quick positioning can be performed through text content, which greatly improves the efficiency of system use.
作为一种可选的实施方式，所述方法还包括：As an optional implementation, the method also includes:

通过所述应用程序，对所述本地文件索引中与所述操作事件对应的文件进行更新。The file corresponding to the operation event in the local file index is updated through the application program.
在该可选的实施方式中，在首次加载时，可以通过应用程序将所述文件系统过滤驱动加载到操作系统中，具体的，应用程序可以加载所述文件系统过滤驱动(即win内核模块)，让所述文件系统过滤驱动进入到操作系统的工作空间里后，就成为了操作系统的一部分，与所述操作系统共享一块内存，同属一个进程。所述文件系统过滤驱动工作后，所述文件系统过滤驱动就可以和应用程序直接进行通信。之后，再通过加载后的所述文件系统过滤驱动，监听所述所有文件发生的操作事件，比如：文件创建事件、文件删除事件以及文件修改事件等。当加载后的文件系统过滤驱动监听到这些操作事件时，可以将所述操作事件回调至所述文件系统过滤驱动，并通过所述文件系统过滤驱动将所述操作事件反馈至所述应用程序；最后，再通过所述应用程序，对所述本地文件索引中与所述操作事件对应的文件进行更新。In this optional embodiment, when loading for the first time, the file system filter driver can be loaded into the operating system through the application program, specifically, the application program can load the file system filter driver (ie win kernel module) After the file system filter driver enters the working space of the operating system, it becomes a part of the operating system, shares a piece of memory with the operating system, and belongs to the same process. After the file system filter driver works, the file system filter driver can directly communicate with the application program. After that, the loaded file system filter driver is used to monitor operation events of all files, such as file creation events, file deletion events, and file modification events. When the loaded file system filter driver listens to these operation events, it can call back the operation event to the file system filter driver, and feed back the operation event to the application through the file system filter driver; Finally, the file corresponding to the operation event in the local file index is updated through the application program.
其中，所述应用程序的生命周期、所述文件系统过滤驱动的生命周期以及所述操作系统的生命周期三者保持一致。Wherein, the life cycle of the application program, the life cycle of the file system filter driver and the life cycle of the operating system are consistent.
作为一种可选的实施方式，所述操作事件为文件创建事件，所述通过所述应用程序，对所述本地文件索引中与所述操作事件对应的文件进行更新包括：As an optional implementation manner, the operation event is a file creation event, and updating the file corresponding to the operation event in the local file index through the application program includes:

若所述文件创建事件对应的第一文件为文本文件，更新所述本地文件索引中针对所述第一文件的文件名以及文本内容；或，If the first file corresponding to the file creation event is a text file, update the file name and text content of the first file in the local file index; or,
若所述文件创建事件对应的第一文件为非文本文件，更新所述本地文件索引中针对所述第一文件的文件名。If the first file corresponding to the file creation event is a non-text file, update the file name of the first file in the local file index.
在该可选的实施方式中，当所述文件系统过滤驱动监听到的操作事件为文件创建事件时，表明有用户创建了新文件，该文件创建事件会回调至所述文件系统过滤驱动中，所述文件系统过滤驱动需要将该文件创建事件反馈至所述应用程序，具体的，反馈的内容可以包括但不限于文件创建的时间，文件全路径、文件名称、文件大小、文件属性(可读、可写、隐藏)。In this optional implementation, when the operation event monitored by the file system filter driver is a file creation event, it indicates that a user has created a new file, and the file creation event will be called back to the file system filter driver, The file system filter driver needs to feed back the file creation event to the application program. Specifically, the content of the feedback may include but not limited to the time when the file was created, the full path of the file, the name of the file, the size of the file, and the attributes of the file (readable , writable, hidden).
进一步地，应用程序还需要判断所述文件创建事件对应的第一文件是否为文本文件，具体的，可以根据所述第一文件的文件后缀名、文件大小以及文件存储格式，判断所述第一文件是否为文本文件，具体描述可以参照上文所述的，在此不再赘述。若所述文件创建事件对应的第一文件为文本文件，可以更新所述本地文件索引中针对所述第一文件的文件名以及文本内容；或，若所述文件创建事件对应的第一文件为非文本文件，只需要更新所述本地文件索引中针对所述第一文件的文件名。Further, the application also needs to judge whether the first file corresponding to the file creation event is a text file. Specifically, the first file can be judged according to the file extension, file size, and file storage format of the first file. Whether the file is a text file, the specific description can refer to the above, and will not be repeated here. If the first file corresponding to the file creation event is a text file, the file name and text content of the first file in the local file index may be updated; or, if the first file corresponding to the file creation event is For non-text files, only the file name of the first file in the local file index needs to be updated.
作为一种可选的实施方式，所述操作事件为文件删除事件，所述通过所述应用程序，对所述本地文件索引中与所述操作事件对应的文件进行更新包括：As an optional implementation manner, the operation event is a file deletion event, and updating the file corresponding to the operation event in the local file index through the application program includes:
通过所述应用程序，删除所述本地文件索引中所述文件删除事件对应的第二文件。Through the application program, delete the second file corresponding to the file deletion event in the local file index.
在该可选的实施方式中，当所述文件系统过滤驱动监听到的操作事件为文件删除事件时，表明有用户删除了某个文件，该文件删除事件会回调至所述文件系统过滤驱动中，所述文件系统过滤驱动需要将该文件删除事件反馈至所述应用程序，具体的，反馈的内容可以包括但不限于文件删除的时间，文件全路径、文件名称、文件大小、文件属性(可读、可写、隐藏)。In this optional implementation, when the operation event monitored by the file system filter driver is a file deletion event, it indicates that a user has deleted a certain file, and the file deletion event will be called back to the file system filter driver , the file system filter driver needs to feed back the file deletion event to the application program.

本实施例中，所述文件查找装置根据其所执行的功能，可以被划分为多个功能模块。所述功能模块可以包括：接收模块201、搜索模块202及输出模块203。本发明所称的模块是指一种能够被至少一个处理器所执行并且能够完成固定功能的一系列计算机程序段，其存储在存储器中。在一些实施例中，关于各模块的功能将在后续的实施例中详述。In this embodiment, the file search device can be divided into multiple functional modules according to the functions it performs. The functional modules may include: a receiving module 201 , a searching module 202 and an output module 203 . The module referred to in the present invention refers to a series of computer program segments that can be executed by at least one processor and can complete fixed functions, and are stored in memory. In some embodiments, the functions of each module will be described in detail in subsequent embodiments.
接收模块201，用于接收携带有文本关键词的文件查找请求；Receiving module 201, is used for receiving the file search request that carries text keyword;
本发明实施例中，当用户需要查找某个文件时，用户可以在应用层输入携带有文本关键词的文件查找请求。In the embodiment of the present invention, when a user needs to search for a certain file, the user may input a file search request carrying text keywords at the application layer.
其中，所述文本关键词可以为文件名称中的全部或部分关键词，或者，所述文本关键词可以为文件包括的文本内容中的部分关键词。Wherein, the text keywords may be all or part of the keywords in the file name, or, the text keywords may be part of the keywords in the text content included in the file.
作为一种可选的实施方式，所述文件查找装置还包括：As an optional implementation manner, the file search device further includes:
读取模块，用于在所述接收模块201接收携带有文本关键词的文件查找请求之前，读取当前文件系统中的所有文件；A reading module, configured to read all files in the current file system before the receiving module 201 receives a file search request carrying text keywords;
判断模块，用于针对每个所述文件，根据所述文件的文件后缀名、文件大小以及文件存储格式，判断所述文件是否为文本文件；Judging module, for each said file, according to the file suffix name, file size and file storage format of said file, judge whether said file is a text file;
创建模块，用于若所述文件为文本文件，基于所述文件的文件名以及文本内容，创建文本文件索引；Creating a module for creating a text file index based on the file name and text content of the file if the file is a text file;
所述创建模块，还用于若所述文件为非文本文件，基于所述文件的文件名，创建非文本文件索引；The creation module is also used to create a non-text file index based on the file name of the file if the file is a non-text file;
所述创建模块，还用于根据所述文本文件索引以及所述非文本文件索引，创建所述本地文件索引。The creating module is further configured to create the local file index according to the text file index and the non-text file index.
在该可选的实施方式中，以NTFS(New Technology File System，新技术文件系统)为例，大部分windows都是这样的文件系统。NTFS里会维护一张表MTF(Master FileTable，主文件表)，所有的文件夹和文件名称都被存储在该MTF表中，在首次启动时就通过读取该MTF表的内容，获取到所有的文件名称和路径，进一步地，对该所有文件进行筛查，以区分哪些文件是文本文件，哪些文件是非文本文件，并创建本地文件索引。后续如果用户操作文件，可以对本地文件索引进行修改。In this optional implementation manner, NTFS (New Technology File System, new technology file system) is taken as an example, and most windows are such file systems. A table MTF (Master FileTable, master file table) is maintained in NTFS, and all folders and file names are stored in the MTF table, and all files are obtained by reading the contents of the MTF table when starting for the first time. Further, all files are screened to distinguish which files are text files and which files are non-text files, and create a local file index. If the user operates the file later, the local file index can be modified.
通常，文本文件的文件后缀名可以包括但不限于doc、txt、json，非文本文件的文件后缀名可以包括但不限于mp4、avi、mpg、mlv，文本文件所占内存比非文本文件所占内存要小，此外，为了避免恶意将庞大的非文本文件修改成文本文件，还需要对文本文件进行鉴别。Usually, the file suffixes of text files can include but not limited to doc, txt, json, the file suffixes of non-text files can include but not limited to mp4, avi, mpg, mlv, and the memory occupied by text files is higher than that of non-text files The memory should be small. In addition, in order to avoid maliciously modifying huge non-text files into text files, it is also necessary to identify the text files.
其中，每个不同类型的文件，在计算机上的存储会以不同的结构存在，这些各种有规律的结构被描述成文件存储格式，例如：Windows平台的exe，dll，sys文件统称为PE文件，并拥有自己特有的格式，比如文件的前两个字节为4D5A，这是PE文件的标志，再比如MP4格式的文件，第4-7字节的内容就是66 74 79 70。因此，在对文本文件进行鉴别时，还可以根据文件在计算机中的文件存储格式来进行判断，Among them, each different type of file will be stored in a different structure on the computer, and these various regular structures are described as a file storage format, for example: exe, dll, and sys files on the Windows platform are collectively called PE files , and has its own unique format. For example, the first two bytes of the file are 4D5A, which is the symbol of the PE file. For example, the file in MP4 format, the content of the 4th to 7th bytes is 66 74 79 70. Therefore, when identifying a text file, it can also be judged according to the file storage format of the file in the computer,
具体的，针对每个所述文件，可以根据所述文件的文件后缀名、文件大小以及文件存储格式，判断所述文件是否为文本文件，如果所述文件的文件后缀名属于文本文件的文件后缀名，且所述文件的文件大小不超过预设的文本文件大小(比如10M)，且所述文件的文件存储格式为文本文件的文件存储格式，则可以确定所述文件为文本文件，反之，如果所述文件的文件后缀名不属于文本文件的文件后缀名，或所述文件的文件大小超过预设的文本文件大小(比如10M)，或所述文件的文件存储格式为非文本文件的文件存储格式，只要上述三个条件中的任何一个或者任何两个或者三个成立，则可以确定所述文件为非文本文件。Specifically, for each of the files, it can be judged whether the file is a text file according to the file suffix name, file size and file storage format of the file, if the file suffix name of the file belongs to the file suffix of the text file name, and the file size of the file does not exceed the preset text file size (such as 10M), and the file storage format of the file is the file storage format of the text file, then it can be determined that the file is a text file, otherwise, If the file extension of the file does not belong to the file extension of the text file, or the file size of the file exceeds the preset text file size (such as 10M), or the file storage format of the file is a non-text file Storage format, as long as any one or any two or three of the above three conditions are satisfied, it can be determined that the file is a non-text file.
在区分文本文件和非文本文件后，针对文本文件，可以基于文件名以及文本内容，创建文本文件索引，针对非文本文件，可以基于文件名，创建非文本文件索引，进而根据所述文本文件索引以及所述非文本文件索引，创建本地文件索引。After distinguishing between text files and non-text files, for text files, a text file index can be created based on the file name and text content, and for non-text files, a non-text file index can be created based on the file name, and then according to the text file index As well as the non-text file index, a local file index is created.
基于上述方式创建的本地文件索引，当输入的文本关键词与文件名匹配时，可以将匹配的文本文件或非文本文件搜索出来，当输入的文本关键词与文本内容匹配时，可以将匹配的文本文件搜索出来。Based on the local file index created in the above way, when the input text keyword matches the file name, the matched text file or non-text file can be searched out; when the input text keyword matches the text content, the matched Text files are searched out.
搜索模块202，用于根据所述文本关键词，在基于文件系统过滤驱动的本地文件索引中进行搜索，获得目标文件，其中，所述目标文件的文件名与所述文本关键词匹配，或，所述目标文件的文本内容与所述文本关键词匹配；The search module 202 is configured to search the local file index based on the file system filter driver according to the text keyword to obtain the target file, wherein the file name of the target file matches the text keyword, or, The text content of the target file matches the text keywords;
本发明基于windows的文件系统过滤驱动MiniFilter对本地文件索引包括的文件的操作事件进行监听。在操作系统的底层插入一个MiniFilter模块，那么文件的创建、删除、修改以及查看操作成功前的动作消息会被该MiniFilter模块过滤，用户可以选择拦截或者放行，同时也可以获取到文件的全路径、名称、内容以及属性等信息。The present invention is based on the windows file system and drives the MiniFilter to monitor the operation events of the files included in the local file index. Insert a MiniFilter module at the bottom layer of the operating system, then the action messages before the file creation, deletion, modification, and viewing operations are successful will be filtered by the MiniFilter module, and the user can choose to intercept or release, and can also obtain the full path of the file, Information such as name, content, and attributes.
由于本地文件索引是基于文件系统过滤驱动的，无论之前的用户对文件做什么操作(创建、删除、修改)均可以被文件系统过滤驱动监听，进而修改本地文件索引，以实时更新本地文件索引。后续用户输入文本关键词进行查找时，电子设备就可以从文件名以及文本内容两个方面进行查找，以搜索出文件名与所述文本关键词匹配的目标文件，或者，搜索出文本内容与所述文本关键词匹配的目标文件。即，所述目标文件的文件名与所述文本关键词匹配，或，所述目标文件的文本内容与所述文本关键词匹配。Since the local file index is driven based on the file system filter, no matter what operations (create, delete, modify) the previous user does to the file, it can be monitored by the file system filter driver, and then the local file index can be modified to update the local file index in real time. When the user enters the text keyword to search, the electronic device can search from the two aspects of the file name and the text content, so as to search out the target file whose file name matches the text keyword, or search out the text content matching the text keyword. The target file matching the keyword in the above text. That is, the file name of the target file matches the text keyword, or the text content of the target file matches the text keyword.
本发明中，可以高效精准的查找文件系统中的所有相关文件，以最快的速度从驱动层(即文件系统过滤驱动)拿到最精准文件的信息，同时，支持多种方式查找文件，也可以通过文本内容进行快速定位，大大提高系统使用的效率。In the present invention, all related files in the file system can be searched efficiently and accurately, and the most accurate file information can be obtained from the driver layer (ie file system filter driver) at the fastest speed. Quick positioning can be performed through text content, which greatly improves the efficiency of system use.
