Embodiment
Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail.Although shown exemplary embodiment of the present disclosure in the accompanying drawing, yet should be appreciated that and to realize the disclosure and the embodiment that should do not set forth limits here with various forms.On the contrary, it is in order to understand the disclosure more thoroughly that these embodiment are provided, and can with the scope of the present disclosure complete convey to those skilled in the art.
In embodiments of the present invention, in order to help the user that the file in the disk is managed, can at first get access to the attribute information of each file in the disk, therefrom select some file destinations according to certain strategy, then attribute and the descriptor thereof with these file destinations represents to the user, simultaneously, can also provide the deletion of file entrance in the interface in representing of file, the user can be by file descriptor etc. to determine which file be to need deletion, then just can specify deletion action by the deletion entrance of correspondence, and need not be by the deletion action of conventional mode execute file.Wherein, so-called conventional mode just refers to find according to the path of file to be deleted the catalogue at file place, the manual deletion action of execute file (in right-click menu, select " deletion " option after comprising filesselected, perhaps use the mode of Macintosh " shift+delete " that the file of choosing is deleted etc.) again.As seen, the method for the embodiment of the invention can provide a kind of approach that arranges the document easily, can improve the implementation efficiency of file consolidation.Below just the method is at length introduced by step.
Referring to Fig. 1, the file clean-up method that the embodiment of the invention provides can may further comprise the steps:
S101: the attribute information that obtains each file in the disk;
In embodiments of the present invention, in order to help the user file in the disk is managed, at first need to obtain the attribute information of each file in the disk, for example, comprise size, title, path of each file etc.During specific implementation, can adopt various ways to obtain the attribute information of each file in the disk, for example, can directly enumerate the All Files on the disk, but this be a process very consuming time.Consider the importance of search efficiency, the embodiment of the invention can adopt the getattr information of inquiry MFT (Master File Table, MFT) mode.Wherein, based on the way to manage of Windows to disk file, MFT is the index of each file on the disk, and MFT is the in store one group of record that is called " attribute " of each file, each property store dissimilar information.In other words, MFT is the index file of all objects of storing in the Map Disk.In MFT, each file on the disk (comprising MFT self) has a mapping item at least.Every among the MFT comprises following data: size, time and timestamp, security attribute, Data Position etc.Obtain the attribute information of file by only inquiring about this index information, compare with overall retrieving files, on search efficiency, can be greatly improved.
S102: choose attribute information and meet the file of prerequisite as file destination;
On getting access to disk after the attribute information of each file, select the file that may impact system performance in the multifile of need to comforming, take up room larger and general useless file such as some.That is to say, be not take up room larger All Files can be deleted, some file is some system core file or vital documents, in case deleted, will cause system file to be lost or other problems may occur.Therefore, how reasonably to represent the file that may affect system performance to the user, protect simultaneously some system core files and vital document can not to be deleted by mistake, just become extremely important.
For this reason, in embodiments of the present invention, can set in advance the condition of selection, for example, at first can carry out preliminary election to file according to the size of file, select some files undetermined.As, selecting the file of preset number of file size maximum as file undetermined, also namely also file can be sorted from big to small, take out front 1000 (perhaps other numbers) files as file undetermined; Perhaps, also can select file size greater than the file of certain preset threshold value as file undetermined, etc.
After selecting file undetermined, again can be according to path, place catalogue, filename, suffix name and/or the file type of file etc. information, from file undetermined, filter out system core file and vital document, remaining file is defined as described file destination.Wherein, the size of file, path, place catalogue, filename, suffix name, file type etc. all belong to the attribute information of file, can get access to from step S101.
Wherein, according to path, place catalogue, filename, suffix name and/or the file type of file etc. information, when from file undetermined, filtering out system core file and vital document, can rule of thumb wait in advance and set white list, if a certain attribute of certain file hits white list, then can be counted as system core file or vital document.Wherein, be used for preserving some in the white list and may belong to the file characteristic of system core file or vital document, like this, just the feature in each file undetermined and the white list can be mated, if the match is successful, then can be used as system core file or vital document.During specific implementation, white list can exist with forms such as library files (such as the data file), and can encrypting storing.
Wherein, for the system core file, namely refer to play for the normal operation of system the file of key effect, in case these files are deleted or lose, then can be so that certain risk of systems face.Specifically when being set, white list can comprise:
The path white list can be preserved some specific key words in this white list, if find to comprise in the path of certain file certain special key words in the white list, namely can be used as the system core file and be filtered.The catalogue white list is preserved some specific catalogues in this white list, if the catalogue at certain file place appears in this white list, then can be used as the system core file and be filtered.Such as the All Files in the system directory of Windows all as the system core file, etc.
Suffix name, filename white list, preserve some specific suffix name or filenames in this white list, namely suffix name or the filename according to file filters file, if the suffix name of certain file has been hit white list, then is used as the system core file and is filtered.In addition, some system's specific properties files can directly be listed in the white list of filename, such as desktop.ini etc.
During specific implementation, each white list can arrange respectively, each file can be mated with each white list respectively like this, and hitting wherein, any white list can be filtered out.
For example, the structure of path white list can be as follows:
The structure of filename white list can be as follows:
The structure of suffix name white list can be as follows:
In addition, in order to raise the efficiency, also can filter by the mode of canonical coupling, also namely can create regular expression according to path, filename, file type etc. attribute, then each file and this regular expression are mated, match arbitrary regularity conditions, can be filtered and to show as the system core file.For example, a kind of regular expression can for:
＜spefileitem filename=" * KB936929* " dir=" " des=" Windows XP SP3 patch file "/〉
The meaning of this regular expression is, (also can comprise other characters in " * " expression filename in the expression formula if comprise " KB936929 " in the filename of certain file, as long as namely hit this condition comprising " KB936929 " this character string), perhaps descriptor is " Windows XP SP3 patch file ", then can be used as the system core file and is filtered.
These safeguard measures can all be shielded the large file that may cause serious problems to a great extent, thereby what allow the user sees is the file that really can delete.
In addition, about vital document, generally refer to important for the user and for useful file.The deletion of this class file can not cause computer system to go wrong, but may be the data that the user needs, rather than junk data, and mistake also can cause the user to perplex after deleting.Mainly can differentiate and filter by the type suffix name white list of file for this class file.Generally be vital document such as history file of database file, professional software etc., then the suffix name of database file, the suffix name of professional software history file can be joined in the white list.As the word document take .doc or .docx etc. as the suffix name, this class document generally is user's file of editing or downloading etc., generally may be useful, therefore, .doc, the suffix name such as .docx just can join in the white list, the file that the suffix name is hit this white list can be used as vital document and filter out.For example, the structure of file type white list can be as follows:
In a word, no matter be that system core file or vital document can filter by the mode of white list.These file filters are fallen not to be shown to the user, deleted to avoid it by mistake.
Certainly, in actual applications, except can filtering file by the mode of white list, can also filter file by the mode of blacklist.Certainly, adopting under the filter type of blacklist, what preserve in the blacklist is some characteristic attributes that can be shown to user's file, also is that the file that attribute information hits blacklist is the file that need to be shown to the user.That is to say, after selecting the larger file undetermined that takes up room, can remove selective system critical file or vital document by the mode of white list, again it is filtered out, but can from file undetermined, select the file that has hit the blacklist rule, with it as influential to system performance and can represent to the user by deleted file.When creating blacklist, can create according in the past experience etc., for example, the catalogue at system disk (generally being the C dish) inner common garbage files place comprises following:
Cookies records (c:Documents and Settings user name Cookies);
Windows user's temporary folder (c:Documents and Settings user name LocalSettingsTemp);
Browser rs cache catalogue (c:Documents and Settings user name LocalSettingsTemporaryInternet Files);
The history file record (All Files under the c:Documents and Settings user name LocalSettingsHistory) of opening recently;
The historical shortcut record (All Files under the c:Documents and Settings user name Recent) of opening recently;
Windows temp directory (All Files under the c:WINDOWSTemp);
Windows upgrades patch catalogue (All Files under the c:WINDOWSSoftwareDistributiondownload);
Above file generally all is to take up room greatlyr, and system is not still all had the file of too large use to the user, therefore, can according to the information creating blacklists such as its path, catalogue rule, be used for file undetermined is filtered.
Need to prove, in actual applications, be used for the presetting rule that file is filtered, can manually be arranged according to actual needs by the user, and corresponding entrance can be provided, allow the new rule of user add, perhaps delete, change original rule, etc.
S103: obtain the descriptor of each file destination and represent;
After the file destination of having determined to represent to the user, just can represent file destination.In embodiments of the present invention, the base attribute information such as filename, path that can not only represent each file destination, can also get access to the descriptor of each file destination, descriptor is also represented to the user, like this, the user can with reference to the descriptor of each file destination, judge whether to carry out deletion action.Descriptor can be for the descriptive information of statement file effect and/or be used for the descriptive information of the consequence that may cause after the statement deletion, comprises namely also after the purposes, deletion of file what impact etc. is arranged.Wherein, each file of storing at disk generally all can be preserved the descriptor to each file simultaneously, therefore, can therefrom directly obtain the descriptor of each file, perhaps, also can obtain the descriptor of mating with file destination according to the descriptor of the various files of preserving on the server, etc.
S104: for described file destination provides the deletion entrance, when receiving removal request with box lunch by described deletion entrance, the file destination of correspondence is deleted.
When representing file destination and descriptor thereof to the user, the operation entry of deleted file can also be provided to the user, when if the user deletes certain file according to definite needs such as descriptor of each file like this, just can directly send the deletion indication from this entrance, afterwards just can be automatically according to the path of file etc. finding corresponding file, and carry out deletion action.As seen, in this process, do not need again locating file in the concrete disk of user, manually carrying out deletion, made things convenient for user's operation, can improve the implementation efficiency of file consolidation.
In actual applications, when representing the descriptor of each file destination and correspondence thereof to the user, can represent in the mode of tabulation, shown in the left part of Fig. 2, as seen in this tabulation, show the attribute information such as Disk name, size at filename, the place of each file destination, about the descriptor of file, can when the user will operate Focal Point Shift to certain file place clauses and subclauses, show in modes such as pop-up windows.For example, in Fig. 2, when mouse being moved on " enterww.cab " this file, will below these clauses and subclauses, demonstrate a rectangle frame, wherein demonstrate descriptor, comprise fullpath of this document and uses thereof, such as " office installation file ".Perhaps, for more directly perceived, in embodiments of the present invention, can also add up respectively according to the type of each file destination the big or small summation of all kinds file, and the big or small summation of all kinds file shared ratio in the big or small summation of target complete file, then according to the shared ratio of all kinds file, represent in the more intuitive mode such as histogram, bar chart, pie chart, ring-type figure.For example, shown in the right side of Fig. 2 is divided, situation about representing with the mode of ring bodies exactly.For ease of introducing, can be referring to Fig. 3, be the equal of right side among Fig. 2 to be divided amplify display effect afterwards, as can be seen from Figure 3, statistics be file destination be divided into document, image, video, music, compression, other etc. six classes, in ring-type figure, can represent with different colors different types, different region areas represents the shared ratio of each type file.Need to prove, owing to can only illustrate with black and white picture in the accompanying drawing, therefore, mode with lead-in wire illustrates the respectively file type of correspondence of regional, in actual applications, this lead-in wire can show, but can work as mouse when entering a certain zone, demonstrate the file type of this zone correspondence in ring-type center of graph zone, and shared ratio.For example, in Fig. 3, mouse enters " other " file area, then demonstrate in the central area " other, 1.3GB ".If mouse does not enter any zone of ring-type figure, then can demonstrate in the central area total size of the current large file of selecting, for example " add up to big or small 2.8GB ".
Under the ways of presentation of this ring-type figure, when the deletion entrance is provided, total deletion entrance can be provided respectively for the file destination of each type, like this, if the user determines and the file of a certain type all need to be deleted, then can send removal request by total deletion entrance corresponding to the type, when receiving removal request by total deletion entrance, just the file destination of corresponding types all can be deleted, further facilitated user's operation.Certainly, in order to make things convenient for the user Single document is carried out deletion action, can also provide respectively independent deletion entrance for each file.During specific implementation, in the time of can entering in user's operation focus a certain type place regional, the formal expansion of each file in the type with tabulation represented, and in tabulation, be respectively each file this independent operation entry is provided, when receiving removal request by certain independent deletion entrance, just can delete independent file corresponding to entrance to this and delete.Referring to Fig. 4, when the operation focus of passing through the user enters video type place regional, just can in the left window, list the file destination of the type with the form of tabulation, simultaneously, a check box is arranged before each file, if want to delete certain file, then can file to be deleted be chosen by the mode of choosing check box, and in the interface, select to delete by the deletion entrance and get final product.As shown in Figure 5, supposed to choose three video files wherein, then " deletion " button in the upper right corner becomes upstate, clicks this button, can be with these three file deletions.
In a word, pass through the embodiment of the invention, can select some specific files, and file name and descriptor thereof are represented to the user, the deletion entrance of each file is provided simultaneously, like this, when the user need to delete certain file, just can directly enter by this entrance, carry out deletion action, user-friendly, improve the implementation efficiency of file clean-up.In addition, setting by specific rules, can be only will may impact and the file that do not belong to system core file or user's vital document represents to the user system performance, like this, can so that the user see more intuitively can deleted file, avoid system core file or user's vital document deleted.
