In the embodiment of the present invention, methods described can be applied in optimization class software, can also be carried in application program In Unload module, specifically, the embodiment of the present invention is not restricted.For convenience of description, the embodiment of the present invention is to apply in computer On optimization class software in exemplified by, but it should explanation, the embodiment of the present invention is not limited to using in a computer, and do not limit In for optimizing in class software, every device that can implement the embodiment of the present invention is belonged to needed for the embodiment of the present invention The scope of protection.

In the embodiment of the present invention, when receiving cleaning instruction, the inventive method is performed, wherein, the cleaning instruction refers to Instruction for clearing up garbage files.For example：" key cleaning " button in application software " Kingsoft bodyguard " is clicked on, cleaning is sent Instruction, so that computer receives cleaning instruction；Again for example：After COMPUTER DETECTION has been unloaded to application software, automatically initiate clear Reason instruction；Again for example：Computer is periodically executed the cleaning of rubbish, so as to automatically initiate cleaning garbage files every preset duration Cleaning instruction.Specifically, the embodiment of the present invention is not restricted.

S102：Instructed according to the cleaning, by way of scanning registration table, recognize the MSP files of redundancy.

Generally, when the application software based on Windows Installer fabrication techniques is installed, Windows Installer The MSP files of generation can be discharged into %systemroot% backed up in Installer catalogues, the MSP files discharged It can be used for reparation operation of the application software etc., meanwhile, these MSP files synchronously can be also documented in registration table.Wherein, % Systemroot% is a windows system parameter values, represents windows installation directory, and %systemroot% is general In the case of be C:Windows, be also likely to be D according to installation directory difference:\Windows、C:WinXP etc..In general, After the application software unloading of certain MSI type, what the application software of this MSI type was produced or discharge in use owns MSP files can turn into invalid MSP files, accordingly, in registration table the MSP files will be marked to be invalid MSP files.So And, existing software uninstalling method is unloaded after the application software of the type, can't go to be automatically deleted soft with unloaded application The associated MSP files of part, therefore, cause the MSP files of this partial invalidity to take the disk space of computer, increase computer Storage burden.Certainly, also part MSP files are caused to turn into redundant file in the presence of some other situations, for example：Run patch journey During sequence, Windows Installer by the MSP files of generation be discharged into %systemroot% in Installer catalogues, draw Lead the user installation patch, if user guide install during click cancellation operation or patch installs necessary requirement Not enough and cause install failure, Windows Installer will move out installation procedure, by be discharged into %systemroot% MSP files inside Installer catalogues are remained；When user runs same patch again, Windows Installer again can %systemroot% the (filename and upper of new MSP files of generation one inside Installer catalogues Difference once), the MSP files without the MSP files produced using last time release, therefore last release generation also will MSP files as redundancy.

In the embodiment of the present invention, receive after cleaning instruction, scan registration table, recognize the MSP files of redundancy, so that, lead to The MSP files of redundancy on the mode of registration table, identification computer are over-scanned, recognize that the speed of the MSP files of redundancy is fast, efficiency It is high.

What deserves to be explained is, the method that the MSP files of redundancy are recognized in the embodiment of the present invention can be direct scanning registration Table obtains MSP files invalid on computer, and accessed invalid MSP files are defined as to the MSP files of redundancy；Also may be used To be that scanning registration table obtains effective MSP files on computer, excluded from all MSP files on computer accessed Effective MSP files, remaining MSP files may be considered the MSP files of redundancy.Specifically, the embodiment of the present invention is not It is restricted.

S103：Obtain the file name and the store path associated of the MSP files of the redundancy.

After the MSP files that redundancy is recognized by step S102, the MSP of the redundancy is further obtained by way of registration table The file name of file and the store path associated, wherein, the storage associated by the file name and with the file name Path uniquely determines a MSP file.For example：The file name of the MSP files of acquired redundancy is 1fd27a.msp, storage Path is C:Windows the MSP files of Installer, the i.e. redundancy refer to C:\Windows\Installer\ 1fd27a.msp。

S104：According to the file name of the MSP files of the redundancy and the store path associated, the MSP of the redundancy is deleted File.

According to the file name of the MSP files of the step S103 redundancies got and the store path associated, delete this and deposit Store up the MSP files of the file name of the MSP files of the entitled accessed redundancy of file under path.For example：Delete storage road Footpath C:Under Windows Installer the entitled 1fd27a.msp of file MSP files.

In the file clean-up method that the embodiment of the present invention is described, when receiving cleaning instruction, registration table is scanned, is recognized superfluous Remaining MSP files and the file name and the store path associated of the MSP files for obtaining identified redundancy；According to acquired The file name of the MSP files of the redundancy arrived and the store path associated, delete the MSP files of the redundancy.Using of the invention real Example is applied, the degree of accuracy and the efficiency of the MSP files of cleaning redundancy can be improved.

Fig. 2 is referred to, Fig. 2 is a kind of another schematic flow sheet of file clean-up method provided in an embodiment of the present invention, In the embodiment of the present invention, this method may comprise steps of.

S201：The cleaning for clearing up garbage files is received to instruct.

For example：User clicks on " key cleaning " button in application software " Kingsoft bodyguard ", sends cleaning instruction；Computer When detecting the application software of unloading MSI types, the cleaning instruction of cleaning garbage files is automatically initiated；Computer is periodically executed rubbish The cleaning of rubbish, so that, cleaning instruction of cleaning garbage files etc. is automatically initiated every preset duration.In the embodiment of the present invention, The cleaning that computer receives for clearing up garbage files is instructed.

S202：By way of scanning registration table, the state flag bit of MSP files is obtained.

Generally, when the application software based on Windows Installer fabrication techniques is installed, Windows Installer The MSP files of generation can be discharged into %systemroot% backed up in Installer catalogues, the MSP files can be used Operated in the reparation of the software etc., accordingly, these MSP files synchronously can be also documented in registration table.In general, certain money After the application software unloading of MSI types, all MSP that the application software of this MSI type is produced or discharged in use File can turn into invalid MSP files, accordingly, in registration table the MSP files will be marked to be invalid MSP files.However, Existing software uninstalling method is unloaded after the application software of the type, can't go to be automatically deleted and unloaded application software phase The MSP files of association, therefore, cause the MSP files of this partial invalidity to take the disk space of computer, increase depositing for computer Storage burden.In the embodiment of the present invention, receive after cleaning instruction, scan registration table, recognize the MSP files of redundancy, so that, pass through The MSP files of redundancy on the mode of registration table, identification computer are scanned, recognize that the speed of the MSP files of redundancy is fast, efficiency high.

For example：Each MSP files institute of different application software under currently logged on user is obtained by way of scanning registration table Including sub-key in numerical designations be " State " numeric data, for convenience of description, such as obtained by way of scanning registration table The numeric data of following sub-key：HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\Installer\UserData\S-1-5-18\Products\ 00002109150000000000000000F01FEC Patches institute under 5A9E342B77DEB1F43B834268DF28CD58 Including sub-key in numerical designations be " State " numeric data.What deserves to be explained is, in above-mentioned registration table path, sub-key The first sub-key " S-1-5-18 " under " UserData " represents the second sub-key under User logs in mark, sub-key " Products " " 00002109150000000000000000F01FEC " represents the exclusive identification code of the application software of MSI types, sub-key The 3rd sub-key " 5A9E342B77DEB1F43B834268DF28CD58 " under " Patches " represents related to the application software The exclusive identification code of MSP files.Understand, in registration table, MSI files and MSP files pass through the exclusive identification code of file respectively To distinguish.What deserves to be explained is, in actual process, the title of the first sub-key, the second sub-key and the 3rd sub-key is by reality Situation determines, the titles of these three sub-keys respectively by active user's mark of log into thr computer, the application software of MSP types only The exclusive identification code of one identification code and MSP files is determined.

S203：If the value for identifying the state flag bit is preset value, the MSP files that the MSP files are redundancy are determined, Wherein, it is invalid MSP files that the MSP files are represented when the value of the state flag bit of MSP files is the preset value.

Generally, registration table is when marking MSI files and MSP files, if user unloads some MSI file, corresponding application is soft Part, then change the state flag bit of the MSP file relevant with the application software in registration table, the value of the state flag bit is changed For preset value, so that, the value of the state flag bit of MSP files represents that the MSP files are invalid MSP texts when being the preset value Part.In the embodiment of the present invention, after the state flag bit for getting MSP files by step S202, the value of the state flag bit is recognized Whether it is preset value, if, it is determined that the MSP files are the MSP files of redundancy；If it is not, then can not directly determine the MSP files Whether the MSP files of redundancy, can use correlation technique further recognize the MSP files whether for redundancy MSP files, Can be without further identification, specifically, the embodiment of the present invention is not restricted.But, it is preferred that it can use such as Fig. 2 a institutes The method shown further is recognized to the MSP files that the value of state flag bit is not the preset value, recognizes that the MSP files are The no MSP files for redundancy.

For example：For convenience of description, it is assumed that get HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\ 00002109150000000000000000F01FEC\Patches\5A9E342B77DEB1F43B834268DF28CD58

" State "=" 2 "

Wherein, sub-key " State " is the state flag bit of MSP files, in the embodiment of the present invention, for convenience of description, it is assumed that Preset value is 2, then can determine that the MSP files that exclusive identification code is " 5A9E342B77DEB1F43B834268DF28CD58 " are The MSP files of redundancy.

S204：Obtain the file name and the store path associated of the MSP files of the redundancy.

The MSP files of redundancy according to determined by step S203, by way of scanning registration table, further obtain this superfluous The file name of remaining MSP files and the store path associated.

For convenience of understanding, continuation is illustrated with above-mentioned example, and getting exclusive identification code by step S203 is After the MSP files of " 5A9E342B77DEB1F43B834268DF28CD58 " is the MSP files of redundancy, registration table is scanned, is obtained For pointing to, local exclusive identification code is believed for the path of the MSP files of " 5A9E342B77DEB1F43B834268DF28CD58 " Breath.For example：The numeric data of following sub-key is obtained by way of scanning registration table：HKEY_LOCAL_MACHINE\ SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\ Patches in sub-key included under 5A9E342B77DEB1F43B834268DF28CD58 numerical designations be The numeric data of " LocalPackage ", wherein, in the sub-key " S-1-5-18 " and step S203 under sub-key " UserData " The title of the first sub-key under sub-key " UserData " is identical, the sub-key under sub-key " Patches " " 5A9E342B77DEB1F43B834268DF28CD58 " and the name of the second sub-key under the sub-key " Patches " in step S203 Claim identical.

Assuming that get HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows CurrentVersion\Installer\UserData\S-1-5-18\Patches\ 5A9E342B77DEB1F43B834268DF28CD58

" LocalPackage "=" C:\Windows\Installer\2f046.msp”

Then understand, exclusive identification code is the MSP files of the redundancy of " 5A9E342B77DEB1F43B834268DF28CD58 " File name be 2f046.msp, store path associate with the file name of the MSP files be C:\Windows\ Installer。

S205：According to the file name of the MSP files of the redundancy and the store path associated, the MSP of the redundancy is deleted File.

According to the file name of the MSP files of the step S204 redundancies got and the store path associated, delete this and deposit Store up the MSP files of the file name of the MSP files of the entitled accessed redundancy of file under path.For example：Delete storage road Footpath C:Under Windows Installer the entitled 2f046.msp of file MSP files.What deserves to be explained is or root According to the routing information of the MSP files of accessed redundancy, such as C:Windows Installer 2f046.msp, directly delete The MSP files of the redundancy.

What deserves to be explained is, before the MSP files of redundancy are deleted, can also according to the file names of the MSP files and Store path, detects that the MSP files of the entitled file name specified of file in the store path specified whether there is, if depositing Then deleting the MSP files.

In the file clean-up method that the embodiment of the present invention is described, when receiving cleaning instruction, registration table is scanned, is recognized superfluous Remaining MSP files and the file name and the store path associated of the MSP files for obtaining identified redundancy；According to acquired The file name of the MSP files of the redundancy arrived and the store path associated, delete the MSP files of the redundancy.Using of the invention real Example is applied, the degree of accuracy and the efficiency of the MSP files of cleaning redundancy can be improved.

What deserves to be explained is, in the above-described embodiments, after the state flag bit that MSP files are obtained according to step S202, Can also not be the preset value to the value of state flag bit if the value for identifying the state flag bit is not the preset value MSP files determined whether, recognize the MSP files whether be redundancy MSP files.As shown in Figure 2 a, Fig. 2 a are Fig. 2 The schematic flow sheet of the method for the one of which identification redundant file of offer, this method may comprise steps of.

S202a：The value for obtaining state flag bit is not the fileinfo of the MSP files of the preset value, this document information File name and the store path associated including the MSP files.

After the state flag bit for getting MSP files by step S202, if the value of accessed state flag bit is not The preset value, obtains the fileinfo of the MSP files, and this document information includes the file names of the MSP files and associated Store path.

For example：For convenience of description, it is assumed that get HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\ 68AB67CA7DA72502B744BA0000000010\Patches\68AB67CA7DA700005205A7C804100180

" State "=" 1 "

Understand, the value of the state flag bit is not the preset value pre-set, then further obtaining exclusive identification code is The file name of the MSP files of " 68AB67CA7DA700005205A7C804100180 " and the store path associated.

For example：Assuming that get HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows CurrentVersion\Installer\UserData\S-1-5-18\Patches\ 68AB67CA7DA700005205A7C804100180

" LocalPackage "=" C:\Windows\Installer\16957b5.msp”

Then understand, exclusive identification code is the file of the MSP files of " 68AB67CA7DA700005205A7C804100180 " Entitled 16957b5.msp, the store path associated with the file name of the MSP files is C:\Windows\Installer.

S202b：The fileinfo of effective MSP files is obtained, this document information includes the text of the effective MSP files Part title and the store path associated.

Generally, effective MSP file consolidations record is led under a certain path, therefore in the embodiment of the present invention in registration table The mode of overscanning registration table obtains the fileinfo of effective MSP files.

For example：Obtained by way of scanning registration table in the sub-key " SourceList " included by effective MSP files Numerical designations are the numeric data of " PackageName ", for convenience of description, following son are such as obtained by way of scanning registration table The numeric data of key：

HKEY_CLASSES_ROOT\Installer\Patches\DC3BF90CC0D3D2F398A9A6D1762F70F3\ SourceList

" PackageName "=" KB958481.msp "

What deserves to be explained is, the 4th sub-key under sub-key " Patches " " DC3BF90CC0D3D2F398A9A6D1762F70F3 " represents the exclusive identification code of effective MSP files.In actual treatment mistake Cheng Zhong, the title of the 4th sub-key determines by actual conditions, generally, HKEY_CLASSES_ROOT Installer Patches' The fileinfo of the MSP files of mass efficient can be recorded under registration table path.

Further, the effective MSP that file name is " KB958481.msp " is obtained by way of scanning registration table The store path of file association, such as：HKEY_CLASSES_ROOT\Installer\Patches\ DC3BF90CC0D3D2F398A9A6D1762F70F3\SourceList\Net

" 1 "=" C:\windows\system32\installer\KB958481.msp”

So as to, it is known that, the file name of effective MSP files is KB958481.msp, and store path associated with it is C:\windows\system32\installer。

S202c：If the value of state flag bit be not the MSP files of the preset value fileinfo with it is described effective The fileinfos of MSP files is mismatched, during the value for determining state flag bit is not the fileinfo of MSP files of the preset value MSP files corresponding to unmatched fileinfo are the MSP files of redundancy.

For example：The routing information of the MSP files, such as C are constructed with the store path associated according to file name:\ Windows system32 installer KB958481.msp, the value for comparing state flag bit is not the MSP of the preset value The routing information of file whether there is in the routing information of the fileinfo of effective MSP files, if in the presence of matching；If It is not present, then mismatches.

Again for example：Can also be by the value of the step S202a state flag bits got be not the preset value MSP text The fileinfo of part is believed as shown in first group of data in table 1 by the file of the step S202b effective MSP files got Breath is as shown in second group of data in table 1.Recognize wall scroll data in table 1 in first group of data whether with second group of data A wherein data is matched, if there are the data as the wall scroll data in first group of data, i.e. file in second group of data Title and the store path all same associated, then the wall scroll data in first group of data and second group of Data Matching, so as to Using the MSP files specified by this group of data for determining to match in first group of data as effective MSP files；If in second group of data In the absence of the wall scroll data in first group of data, that is, there is file name and/or store path is differed, then can determine first The MSP files specified by the wall scroll data in group data are not effective MSP files, further be can determine that in first group of data The wall scroll data specified by MSP files be redundancy MSP files.

The one of which fileinfo provided in an embodiment of the present invention of table 1

In table 1, first group of data refers to that the value of state flag bit is not the file letter of the MSP files of the preset value Breath, second group of data refer to the fileinfo of effective MSP files.As it can be seen from table 1 only first number in first group of data According to being present in second group of data, i.e., file name is " 16957b5.msp ", and store path is " C:\Windows\ Installer”；Although there is the MSP files that file name is " 1fd2c6.msp " in second group of data, however, second group of number Differed according to the store path and the store path in first group of data of middle this document.Therefore, it is known that, in the Status Flag of table 1 During the value of position is not the fileinfo of MSP files of the preset value, only file name for " 16957b5.msp " MSP texts Part is effective MSP files, and file name can be defined as superfluous for the MSP files of " 1fd2c6.msp " or " 1fd25e.msp " Remaining MSP files.

Fig. 3 is referred to, Fig. 3 is a kind of another schematic flow sheet of file clean-up method provided in an embodiment of the present invention, In the embodiment of the present invention, this method may comprise steps of.

S301：The cleaning for clearing up garbage files is received to instruct.
