Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In the embodiment of the present invention, in order to help a user manage files in a disk, attribute information of each file in the disk may be first obtained, some target files are selected from the target files according to a certain policy, then attributes and description information of the target files are displayed to the user, meanwhile, a deletion entry of the file may be provided in a display interface of the file, the user may determine which files need to be deleted through the description information of the file, and the like, and then may specify a deletion operation through the corresponding deletion entry, instead of executing the deletion operation of the file in a conventional manner. The conventional method is to find a directory where a file is located according to a path of the file to be deleted, and then manually execute a file deletion operation (including selecting a "delete" option in a right-click menu after selecting the file, or deleting the selected file in a manner of using a combination key "shift + delete", or the like). Therefore, the method provided by the embodiment of the invention can provide a convenient way for arranging the files, and can improve the implementation efficiency of file arrangement. The method is described in detail in steps below.

Referring to fig. 1, a file cleaning method provided in an embodiment of the present invention may include the following steps:

s101: acquiring attribute information of each file in a disk;

in the embodiment of the present invention, in order to help a user manage files in a disk, first, attribute information of each file in the disk needs to be acquired, for example, including a size, a name, a path, and the like of each file. In a specific implementation, the attribute information of each file in the disk may be obtained in various ways, for example, all files on the disk may be enumerated directly, which is a very time-consuming process. In consideration of the importance of the query efficiency, the embodiment of the present invention may obtain the attribute information in a manner of querying an MFT (Master File Table). Based on the management mode of Windows on disk files, MFT is the index of each file on the disk, and holds a set of records called attributes for each file, where each attribute stores different types of information. In other words, the MFT is an index file that maps all objects stored in the disk. In MFT, there is at least one map entry for each file on disk (including the MFT itself). Each entry in the MFT contains the following data: size, time and timestamp, security attributes, data location, and the like. By only inquiring the index information to obtain the attribute information of the file, the inquiring efficiency is greatly improved compared with the full-disk file searching.

S102: selecting a file with attribute information meeting preset conditions as a target file;

after acquiring the attribute information of each file on the disk, it is necessary to select a file that may affect the system performance from many files, such as some files that occupy a large space and are generally useless. That is, not all files with large occupied space can be deleted, and some files are some system key files or important files, and once deleted, the system files will be lost or other problems may occur. Therefore, it becomes very important to reasonably present files that may affect the performance of the system to the user, while protecting some system critical files and important files from being deleted by mistake.

For this reason, in the embodiment of the present invention, a selection condition may be preset, for example, the file may be preselected according to the size of the file, and some pending files may be selected. If the preset number of files with the largest file size is selected as the pending files, the files can be sequenced from large to small, and the top 1000 (or other number) files are taken out as the pending files; or, a file with a file size larger than a certain preset threshold value can be selected as a pending file, and the like.

After the pending file is selected, the system key file and the important file can be filtered from the pending file according to the path of the file, the directory, the file name, the suffix name and/or the file type and other information, and the remaining files are determined as the target file. The size, path, directory, file name, suffix name, file type, and the like of the file all belong to the attribute information of the file, and can be obtained from step S101.

When a system key file and an important file are filtered from a pending file according to information such as a path of the file, a directory of the file, a file name, a suffix name and/or a file type, a white list can be set in advance according to experience and the like, and if a certain attribute of a certain file hits the white list, the file can be regarded as the system key file or the important file. The white list is used for storing some file characteristics which may belong to system key files or important files, so that each pending file can be matched with the characteristics in the white list, and if the matching is successful, the pending file can be used as the system key file or the important file. In a specific implementation, the white list may exist in the form of a library file (e.g., a data file) or the like, and may be stored in an encrypted manner.

In this case, the system is exposed to some risk if the critical files of the system, that is, the files that play a critical role in the normal operation of the system, are deleted or lost. Specifically, the setting of the white list may include:

and if the path of a certain file contains a certain keyword in the white list, the certain keyword can be filtered out as a system key file. The file system comprises a directory white list, wherein specific directories are stored in the white list, and if the directory where a certain file is located appears in the white list, the directory white list can be used as a system key file to be filtered. Such as Windows, all files in the system directory as system critical files, and so on.

Suffix name, file name white list, some specific suffix names or file names are stored in the white list, that is, the files are filtered according to the suffix names or file names of the files, if the suffix name of a certain file hits the white list, the file is filtered as a system key file. In addition, some system specific attribute files may be listed directly in a white list of file names, such as desktop.

In specific implementation, each white list can be set respectively, so that each file can be matched with each white list respectively, and any hit white list can be filtered out.

For example, the structure of the path white list may be as follows:

the structure of the file name white list may be as follows:

the structure of the suffix name whitelist may be as follows:

in addition, in order to improve efficiency, filtering may also be performed in a regular matching manner, that is, a regular expression may be created according to attributes such as a path, a file name, a file type, and the like, and then each file is matched with the regular expression, and matched to any regular condition, may be filtered out as a system key file and not displayed. For example, one regular expression may be:

< spafilitem filename ". times.kb 936929". times.dir ". times.des ═ Windows XP SP3 patch file"/>

The regular expression means that if the file name of a certain file includes "KB 936929" (the "+" in the expression indicates that the file name may also contain other characters, as long as the string including "KB 936929" hits the condition), or the description information is "Windows XP SP3 patch file", the file can be filtered out as a system key file.

These protective measures can to a large extent mask large files that may cause serious problems, so that the user sees what is really a file that can be deleted.

In addition, the important file generally means a file that is important and useful for the user. Deletion of such files does not cause problems in the computer system, but may be data required by the user, rather than garbage data, and may cause user trouble after mistaken deletion. For such files, discrimination and filtering can be mainly performed through a suffix name list of the types of the files. For example, database files, archived files of professional software, etc., are typically important files, the suffix name of the database file, the suffix name of the archived file of professional software, etc., may be added to the white list. If a word document generally takes doc or docx and the like as suffix names, the document is generally a file edited or downloaded by a user and the like, and generally may be useful, so that the suffix names of doc, docx and the like can be added into a white list, and the file with the suffix name hitting the white list can be filtered out as an important file. For example, the structure of the file type white list may be as follows:

in summary, both the system key files and the important files can be filtered by means of a white list. The files are filtered out and not displayed to the user so as to avoid being deleted by mistake.

Of course, in practical applications, the files may be filtered by a white list, and the files may be filtered by a black list. Certainly, under the filtering mode of the blacklist, some characteristic attributes of the files which can be displayed to the user are stored in the blacklist, that is, the files of which the attribute information hits the blacklist are the files which need to be displayed to the user. That is to say, after the pending files with a large occupied space are selected, the key files or important files of the system can be selected in a white list mode and then filtered out, but the files which hit the black list rule can be selected from the pending files and displayed to the user as the files which have influence on the system performance and can be deleted. When creating the black list, the black list may be created according to past experience, for example, the directory where the common junk files in the system disk (generally, C disk) are located includes the following:

cookies record (c: Cookies of Documents and Settings user names);

windows user temporary folder (c: Documents and Settings user name LocalSettingsTemp);

browser cache directory (c: Documents and Settings user name LocalSettings TemporaryInternet Files);

history file records opened recently (c: all files under Documents and Settings user name localsettingsHistory);

history shortcut records opened recently (c: all files under Documents and Settings user name Recent);

windows temporary directory (c: all files under WINDOWSTemp);

windows update patch directory (c: all files under WINDOWSSOWWARNeDistributionTownload);

the files generally occupy a large space and are not useful for a system or a user, so that a blacklist rule can be created according to information such as a path and a directory of the files and used for filtering the files to be determined.

It should be noted that, in practical applications, the preset rules for filtering the files may be manually set by the user according to practical needs, and corresponding entries may also be provided to allow the user to add new rules, or delete or change original rules, and so on.

S103: acquiring and displaying the description information of each target file;

after the target file that can be presented to the user is determined, the target file can be presented. In the embodiment of the invention, not only the file name, the path and other basic attribute information of each target file can be displayed, but also the description information of each target file can be acquired and displayed to the user, so that the user can refer to the description information of each target file to judge whether to execute the deleting operation. The description information may be explanatory information for describing the action of the file and/or explanatory information for describing the effect that may be caused after deletion, that is, including the use of the file, what effect is exerted after deletion, and the like. In general, each file stored on the disk stores the description information of each file at the same time, so that the description information of each file can be directly obtained from the description information, or the description information matched with the target file can be obtained according to the description information of each file stored on the server, and so on.

S104: and providing a deletion entry for the target file so as to delete the corresponding target file when a deletion request is received through the deletion entry.

When the target file and the description information thereof are displayed to the user, an operation entry for deleting the file can be provided for the user, so that if the user determines that a certain file needs to be deleted according to the description information and the like of each file, a deletion instruction can be directly sent out from the entry, and then the corresponding file can be automatically found according to the path and the like of the file, and the deletion operation is executed. Therefore, in the process, the user does not need to search the file in the specific disk, and the file is deleted manually, so that the user operation is facilitated, and the implementation efficiency of file arrangement can be improved.

In practical applications, when each target file and its corresponding description information are presented to a user, the target files and their corresponding description information may be presented in a list manner, as shown in the left part of fig. 2, it can be seen that attribute information such as a file name, a located disk name, and a size of each target file is presented in the list, and the description information about the file may be displayed in a pop-up window or the like when the user moves an operation focus to an entry where a certain file is located. For example, in fig. 2, when the mouse is moved over the file "enterwww.cab", a rectangular box is shown under the entry, in which descriptive information is shown, including the complete path of the file and its use, such as "office installation file". Or, in order to be more intuitive, in the embodiment of the present invention, the size sum of each type of file and the proportion of the size sum of each type of file in the size sum of all target files may be respectively counted according to the type of each target file, and then the sum is displayed in a more intuitive manner, such as a histogram, a bar graph, a pie chart, a ring chart, and the like according to the proportion of each type of file. For example, as shown in the right-hand portion of fig. 2, this is the case in which the ring-shaped body is present. For convenience of description, referring to fig. 3, it is equivalent to the display effect after enlarging the right part of fig. 2, and as can be seen from fig. 3, the statistical result is that the target file is divided into six categories of document, image, video, music, compression, and others, in the ring diagram, different types can be represented by different colors, and different area areas represent the proportion of each type of file. It should be noted that, since the drawings can only be illustrated by black and white pictures, the file types corresponding to the respective areas are illustrated by using the lead lines, and in practical applications, the lead lines do not need to be displayed, but can display the file types corresponding to a certain area and the occupied proportion thereof in the central area of the annular diagram when the mouse enters the certain area. For example, in FIG. 3, the mouse enters the "other" file area, and "other, 1.3 GB" is displayed in the center area. If the mouse does not enter any area of the ring graph, the aggregate size of the currently selected large files, e.g., "aggregate size 2.8 GB", may be displayed in the center area.

Under the presentation mode of the annular diagram, when the deletion entries are provided, the total deletion entries can be respectively provided for the target files of various types, so that if a user determines that the files of a certain type need to be deleted completely, a deletion request can be sent through the total deletion entries corresponding to the type, when the deletion request is received through the total deletion entries, the target files of the corresponding type can be deleted completely, and the operation of the user is further facilitated. Of course, in order to facilitate the user to delete a single file, separate deletion entries may be provided for each file. In specific implementation, when an operation focus of a user enters an area where a certain type is located, each file in the type can be expanded and displayed in a list form, and the list provides the individual operation entry for each file, so that when a deletion request is received through an individual deletion entry, the individual file corresponding to the deletion entry can be deleted. Referring to fig. 4, when the user enters the area where the video type is located through the operation focus, the target files of the type can be listed in the left window in a list form, meanwhile, a check box is arranged in front of each file, if a file is to be deleted, the file to be deleted can be checked in a mode of checking the check box, and the deletion can be performed through a deletion entry in the interface. As shown in fig. 5, assuming that three video files are selected, the "delete" button in the upper right corner becomes available, and the three files can be deleted by clicking the button.

In short, through the embodiment of the invention, some specific files can be selected, the file names and the description information thereof are displayed to the user, and meanwhile, deletion entries of all the files are provided, so that when the user needs to delete a certain file, the user can directly enter the file through the entry to execute deletion operation, the user operation is facilitated, and the realization efficiency of file cleaning is improved. In addition, through the setting of specific rules, only files which may affect the system performance and do not belong to the system key files or the user important files can be displayed to the user, so that the user can more intuitively see the files which can be deleted, and the system key files or the user important files are prevented from being deleted.
