Detailed description of the invention
It is more fully described the exemplary embodiment of the disclosure below with reference to accompanying drawings.Although accompanying drawing shows the disclosure
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure and should be by embodiments set forth here
Limited.On the contrary, it is provided that these embodiments are able to be best understood from the disclosure, and can be by the scope of the present disclosure
Complete conveys to those skilled in the art.
In embodiments of the present invention, in order to help user that the file in disk is managed, can first obtain
The attribute information of each file in disk, therefrom selects some file destinations according to certain strategy, then by these mesh
Attribute and the description information thereof of mark file are presented to user, at the same time it can also be provide deleting of file in interface in representing of file
Except entrance, by the description information etc. of file, user can determine which file is to need to delete, then by correspondence
Delete entrance and just can specify deletion action, and the deletion action of file need not be performed by the way of conventional.Wherein, so-called normal
The mode of rule refers to the path according to file to be deleted and finds the catalogue at file place, then manually performs the deletion behaviour of file
Make (in right button menu, after including filesselected, to select " deletion " option, or the side with Macintosh " shift+delete "
Formula is by file deletion of choosing etc.).Visible, the method for the embodiment of the present invention can provide a kind of way arranged the document easily
Footpath, it is possible to increase file consolidation realize efficiency.The most just the method is introduced in detail by step.
Seeing Fig. 1, the file clean-up method that the embodiment of the present invention provides may comprise steps of:
S101: obtain the attribute information of each file in disk；
In embodiments of the present invention, in order to help user that the file in disk is managed, it is necessary first to obtain disk
In the attribute information of each file, it may for example comprise the size of each file, title, path etc..When implementing, can adopt
The attribute information of each file in disk is obtained with various ways, for example, it is possible to the All Files directly enumerated on disk, but this
It it is a process the most time-consuming.In view of the importance of search efficiency, the embodiment of the present invention can use inquiry MFT
The acquisition attribute information of (Master File Table, MFT) mode.Wherein, based on the Windows pipe to disk file
Reason mode, MFT is the index of each file on disk, MFT be each file in store one group be referred to as " attribute " record,
Each attribute stores different types of information.In other words, the index literary composition of all objects stored during MFT is a Map Disk
Part.In MFT, at least mapping item of each file (including MFT self) on disk.Every comprising in MFT counts as follows
According to: size, time and timestamp, security attribute, Data Position etc..File is obtained by only inquiring about this index information
Attribute information, compared with retrieval file totally, can be greatly improved on search efficiency.
S102: choose attribute information and meet the file of prerequisite as file destination；
Getting on disk after the attribute information of each file, selecting in the multifile that needs to comform may be to system
The file that performance impacts, the file of the bigger and typically no use that more such as takes up room.It is to say, not
Being that the bigger All Files that takes up room can be deleted, some file is some system core files or important literary composition
Part, is once deleted, it will causes system file to be lost or is likely to occur other problems.Therefore, the most reasonably to
Family represents the file that may affect systematic function, protects some system core files and vital document to be missed simultaneously
Delete, just become extremely important.
To this end, in embodiments of the present invention, the condition of selection can be pre-set, such as, first can be according to file
Size carries out preliminary election to file, selects some files undetermined.As, the file selecting the maximum preset number of file size is made
For file undetermined, namely file can also be ranked up from big to small, take out first 1000 (or other numbers) files and make
For file undetermined；Or, it is also possible to select file size more than the file of certain preset threshold value as file undetermined, etc..
After selecting file undetermined, again can according to the path of file, place catalogue, filename, suffix name and/or
File type etc. information, filters out system core file and vital document from file undetermined, is defined as by remaining file
Described file destination.Wherein, the size of file, path, place catalogue, filename, suffix name, file type etc. broadly fall into literary composition
The attribute information of part, can get from step S101.
Wherein, in the path according to file, place catalogue, filename, suffix name and/or file type etc. information, from
When file undetermined filters out system core file and vital document, white list can be set previously according to experience etc., if certain
The a certain attribute hit white list of file, then can be counted as system core file or vital document.Wherein, white list is used
In preserving some file characteristics that may belong to system core file or vital document, in this manner it is possible to by each literary composition undetermined
Part mates with the feature in white list, if the match is successful, then and can be by as system core file or vital document.Tool
When body realizes, white list can exist with forms such as library files (such as data file), and can be with encrypting storing.
Wherein, for system core file, namely refer to the properly functioning file playing key effect for system,
Once these files are deleted or lose, then can make certain risk of systems face.Specifically can wrap when arranging white list
Include:
Path white list, can preserve some specific keywords in this white list, if it find that in the path of certain file
Comprise certain special key words in white list, can be used as system core file and be filtered.Catalogue white list, in this white list
Preserve some specific catalogues, if the catalogue at certain file place occurs in this white list, then can be as system core
File is filtered.All Files in the system directory of such as Windows all as system core file, etc..
Suffix name, filename white list, preserve some specific suffix name or filenames, i.e. according to literary composition in this white list
File is filtered by suffix name or the filename of part, if the suffix name of certain file has hit white list, then by as system
Critical file is filtered.It addition, some system specific properties files, can directly list in the white list of filename, such as
Desktop.ini etc..
When implementing, each white list can be respectively provided with, so can by each file respectively with each white list
Mating, hit any of which white list can be filtered out.
Such as, the structure of path white list can be such that
<excludeitem keyword=" INFO2 " type=" file " issys=" true "/>is if in/* path
Occur keyword " INFO2 ", file type is " file ", be system file */
<excludeitem keyword=" windows.edb " type=" file " issys=" true "/>
<excludeitem keyword=" program files " type=" dir " issys=" true "/>
<excludeitem keyword=" program files " type=" dir " issys=" false "/>
< excludeitem keyword=" system volume information " type=" dir " issys="
true″/>
< excludeitem keyword=" system volume information " type=" dir " issys="
false″/>
<excludeitem keyword=" boot " type=" dir " issys=" true "/>
<excludeitem keyword=" recovery " type=" dir " issys=" true "/>
<excludeitem keyword=" windows " type=" dir " issys=" true "/>
The structure of filename white list can be such that
<spefileitem filename=" ppsds.pgf " dir=" " des=" PPS Web TV cache file "/>
< spefileitem filename=" Data1.cab " dir=" Adobe Acrobat 9Pro " des="
AdobeAcrobat installs file "/>
< " WinPE boot disk makes literary composition to spefileitem filename=" Data.DND " dir=" Data " des=
Part "/>
< spefileitem filename=" caehe*.dat " dir=" ikudisk " des=" excellent cruel video cache
File "/>
< " excellent cruel video delays spefileitem filename=" cache*.dat " dir=" youkudisk " des=
Deposit file "/>
< spefileitem filename=" Nokia_Suite.msi " dir=" " des=" install by Nokia's PC external member
File "/>
<spefileitem filename=" pak0.pak " dir=" valve " des=" CS game file "/>
< " literary composition is installed in the game of the ninth-largest land to spefileitem filename=" c9_setup_* " dir=" " des=
Part "/>
< spefileitem filename=" QQFFO*install* " dir=" " des=" pacify by the free fantastic play of QQ
Dress file "/>
The structure of suffix name white list can be such that
< speitem filetail=" .msp " des=" Windows program installation package file " type=" installation kit "
Dangrous=" true "/>
< speitem filetail=" .xml " des=" extensible markup language document " type=" file "
Dangrous=" true "/>
< speitem filetail=" .exw " des=" Kinescope: Kinescope Expert associated documents " type=" records a video "
Dangrous=" false "/>
< speitem filetail=" .reg " des=" registry file " type=" registration table " dangrous="
true″/>
It addition, in order to improve efficiency, it is also possible to filter by the way of canonical is mated, namely can according to path,
Filename, file type etc. attribute creates regular expression, is then mated with this regular expression by each file,
It is fitted on arbitrary regularity conditions, can serve as system core file and be filtered and not show.Such as, a kind of regular expression can
Think:
< spefileitem filename=" * KB936929* " dir=" " des=" Windows XP SP3 patch literary composition
Part "/>
The meaning of this regular expression is, if the filename of certain file includes " KB936929 " (" * " in expression formula
Represent in filename and can also comprise other characters, as long as i.e. hitting this condition including " KB936929 " this character string),
Or the information of description is " Windows XP SP3 patch file ", then can be filtered as system core file.
These protective measures can all be shielded the big file being likely to result in serious problems to a great extent, from
And allow user it is seen that the file that really can delete.
It addition, about vital document, generally refer to the most important and for useful file.This class file
Deletion be not result in that computer system goes wrong, but be probably user need data rather than junk data, after deleting by mistake
Will also result in user's puzzlement.Mainly can carry out differentiating and mistake by the type suffix name white list of file for this class file
Filter.The such as history files of database file, professional software etc. are usually vital document, then can be by the suffix of database file
Name, the suffix name of professional software history file join in white list.After as word document with .doc or .docx etc. being
Sewing name, this kind of document is usually the file etc. that user edits or downloads, and is typically probably useful, therefore, and .doc .docx
Just can join in white list etc. suffix name, suffix name is hit the file of this white list and can be filtered as vital document
Fall.Such as, the structure of file type white list can be such that
<subitemfiletype=" .jpg | .jpeg | .png | .psd | .bmp | .GIF | .gif | .psd | .GIFf |
.tga | .exif | .svg | .cdr | .pcd | .dxf | .ufo | .eps | .ai | .raw | " disname=" image " des=" image
File, file " dangrous=" false " colornormal=" 0x00d0fa of common preservation picture in computer "
Colorhover=" 0x00e6ff " coloractive=" 0x00ace5 "/>
In a word, either system core file or vital document can filter by the way of white list.Will
These file filters fall to be not displayed to user, to avoid it to be deleted by mistake.
Certainly, in actual applications, in addition to file can being filtered by the way of white list, it is also possible to logical
File is filtered by the mode crossing blacklist.Certainly, under the filter type using blacklist, preserve in blacklist is can
To be shown to some characteristic attributes of the file of user, namely the file of attribute information hit blacklist is to need to be shown to user
File.It is to say, after selecting the bigger file undetermined that takes up room, can go by the way of white list
Select system core file or vital document, then filter this out, but can select from file undetermined and hit black name
Single gauge file then, as having an impact systematic function and can be presented to user by deleted file.Creating black name
Dan Shi, can create according to conventional experience etc., such as, and system disk (usually C dish) inner common garbage files place
Catalogue includes following:
The own record (c:Documents and Settings user name Cookies) of 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)；
History file record (the c:Documents and Settings user name opened recently
All Files under LocalSettingsHistory)；
The history shortcut record (institute under c:Documents and Settings user name Recent opened recently
There is file)；
Windows temp directory (All Files under c:WINDOWSTemp)；
Windows updates patch catalogue (all literary compositions under c:WINDOWSSoftwareDistributiondownload
Part)；
Above file typically all takes up room bigger, and to system or to user's all not the biggest use
File, therefore, it can according to its information creating blacklist such as path, catalogue rule, for filtering file undetermined.
It should be noted that in actual applications, for the presetting rule that file is filtered, can be by user's root
According to being actually needed manually setting, and may be provided for corresponding entrance, it is allowed to user adds new rule, or delete,
Change original rule, etc..
S103: obtain the description information of each file destination and represent；
After determining the file destination that can be presented to user, it is possible to file destination is represented.At this
In bright embodiment, can not only represent the base attribute information such as the filename of each file destination, path, it is also possible to get
The description information of each file destination, is also presented to user by description information, and so, user is referred to each file destination
Description information, it may be judged whether perform deletion action.Description information could be for state file effect descriptive information and/or
The descriptive information of the consequence that may cause after stating deletion, namely include file purposes, delete after have anything to affect
Etc..Wherein, on disk, each file of storage the most all can preserve the description information to each file simultaneously, therefore, and can
The most directly to obtain the description information of each file, or, it is also possible to according to the description of the various files preserved on server
Information, obtains the description information mated with file destination, etc..
S104: provide for described file destination and delete entrance, in order to when receiving removal request by described deletion entrance
Time, corresponding file destination is deleted.
While file destination and description information thereof are presented to user, it is also possible to provide a user with the behaviour deleting file
Make entrance, if so user determines when needing to delete certain file according to the description information etc. of each file, it is possible to directly
Send deletion instruction from this entrance, the most just can find the file of correspondence automatically according to the path etc. of file, and perform deletion
Operation.Visible, in the process, it is not necessary to user to locating file in concrete disk, is manually performing deletion, facilitating again
User operation, that can improve file consolidation realizes efficiency.
In actual applications, when representing the description information of each file destination and correspondence thereof to user, can be with list
Mode represent, as shown in the left part of Fig. 2, it is seen that show in the list each file destination filename,
The attribute informations such as the Disk name at place, size, about the description information of file, can move to certain user by operation focus
During the entry of file place, show in modes such as pop-up windows.Such as, in fig. 2, mouse is moved to
Time on " enterww.cab " this file, a rectangle frame will be demonstrated below this entry, show description letter
Breath, including the fullpath and application thereof of this document, such as " office installs file ".Or, in order to more directly perceived, real in the present invention
Execute in example, it is also possible to add up the size summation of all kinds file respectively according to the type of each file destination, and various types of
The ratio that the size summation of type file is shared in the size summation of target complete file, then according to shared by all kinds file
Ratio, represent in the more intuitively mode such as block diagram, bar diagram, pie chart, ring-type figure.Such as, such as the right part of Fig. 2
Shown in, it is simply that situation about representing with the mode of ring bodies.Illustratively, can be found in Fig. 3, be the equal of to right side in Fig. 2
Divide the display effect after amplifying, from figure 3, it can be seen that statistical result is file destination is divided into document, image, video, sound
Happy, compression, other etc. six classes, in ring-type figure, different types, different region areas can be represented by different colors
Represent the ratio shared by each type file.It should be noted that owing to accompanying drawing can only be illustrated with black and white picture, therefore, use
The mode of lead-in wire illustrates the file type that regional is the most corresponding, and in actual applications, this lead-in wire can show,
But when can work as the mouse a certain region of entrance, demonstrate, in the central area of ring-type figure, the file type that this region is corresponding, with
And shared ratio.Such as, in figure 3, mouse enters " other " file area, then demonstrate in central area " other,
1.3GB”.If mouse does not enters into any region of ring-type figure, then can demonstrate currently select big in central area
The total size of file, such as, " add up to size 2.8GB ".
Under the ways of presentation of this ring-type figure, when providing deletion entrance, can be that the file destination of each type divides
You can well imagine for total deletion entrance, so, if the user determine that need the file by a certain type all to delete, then can be by being somebody's turn to do
Total deletion entrance corresponding to type sends removal request, when receiving removal request by total deletion entrance, it is possible to
The file destination of corresponding types is all deleted, has further facilitated the operation of user.Certainly, for convenience user to single literary composition
