S101: when scanning storage space, reads the current time stamp of current catalogue to be scanned.

Particularly, in the process that the storage space of mobile terminal to this mobile terminal scans, for current catalogue to be scanned, read the current time stamp of this catalogue.

Wherein, the storage space of mobile terminal can be specially the internal memory in the storage space of nonvolatile memory or mobile terminal.Nonvolatile memory specifically comprises: EEPROM (Electrically Erasable Programmable Read-Only Memory, EEPROM (Electrically Erasable Programmable Read Only Memo)), flash memory, SD (Secure Digital Memory, secure digital memory body) card, micro SD card, memory stick, micro hard disk and solid state hard disc etc.

Preferably, mobile terminal, when scanning storage space, for current catalogue to be scanned, determines the quantity of the file under this catalogue; When determining that the quantity of the file under this catalogue exceedes setting threshold value (such as 2000), read the current time stamp of this catalogue.

S102: for current catalogue to be scanned, the timestamp of this catalogue described in the current time of this catalogue read stamp and scanning being recorded compares, and whether both judgements are consistent, if so, then perform step S103; Otherwise, perform step S106.

Particularly, mobile terminal, for current catalogue to be scanned, finds the timestamp of this catalogue from scanning record, the current time of this catalogue read in the timestamp found and step S101 is stabbed and compares, whether both judgements are consistent, if so, then perform step S103; Otherwise, perform step S106.

Wherein, the timestamp of catalogue recorded in scanning record is that mobile terminal obtains and to should catalogue be recorded to during scanning records in last scan process.

In addition, mobile terminal, for current catalogue to be scanned, if do not find the timestamp of this catalogue from scanning record, then performs step S106.

S103: for current catalogue to be scanned, identifies whether this catalogue is bottom catalogue; If so, step S104 is performed; Otherwise, perform step S105.

S104: for the catalogue being identified as bottom catalogue, skips the scanning to this catalogue, and the information of this catalogue will obtained in last scan process, the information as this catalogue obtained in present scan process carries out record.

Particularly, mobile terminal, for the catalogue being identified as bottom catalogue, skips the scanning to this catalogue, and the information of this catalogue will obtained in last scan process, the information as this catalogue obtained in present scan process carries out record.

The information of catalogue can comprise title and the path of this catalogue; In addition, the information of catalogue can also comprise: the size in the version number of this catalogue, timestamp and shared space, and the title of file in this catalogue, version number, timestamp and shared space size.

S105: for the catalogue being identified as non-bottom catalogue, according to the timestamp of sub-directory under this catalogue, determines the scanning of whether skipping sub-directory under this catalogue.

Particularly, mobile terminal is for the catalogue being identified as non-bottom catalogue, and under this catalogue of continuation acquisition, the current time of each sub-directory is stabbed; For each sub-directory, in the current time of this sub-directory stamp and scanning being recorded, the timestamp of this sub-directory compares; According to comparative result, determine whether to skip specifically to comprise the scanning of this sub-directory:

If if mobile terminal judges that comparative result is consistent, and this sub-directory is bottom catalogue, then skip the scanning to this sub-directory, and the information of this sub-directory will obtained in last scan process, the information as this sub-directory obtained in present scan process carries out record.

If mobile terminal judges that comparative result is inconsistent, then scan this sub-directory, the information of this sub-directory obtained by present scan carries out record.

If mobile terminal judges that comparative result is consistent, and this sub-directory is non-bottom catalogue, then foundation same method is according to the timestamp of each catalogue under this sub-directory, determines the scanning of whether skipping each catalogue under this sub-directory.

Preferably, mobile terminal is for the catalogue current to be scanned being identified as non-bottom catalogue, the level of this catalogue can also be determined, and the current time of each sub-directory is stabbed under determining whether continue to obtain this catalogue according to the level of this catalogue: if the level of this catalogue is less than default number of levels (such as 10 layers), then under this catalogue of continuation acquisition, the current time of each sub-directory is stabbed; Otherwise, the current time stamp of each sub-directory under not continuing to obtain this catalogue.

S106: the inconsistent or Unrecorded current catalogue to be scanned of timestamp for timestamp, scan this catalogue, the information of this catalogue obtained by present scan carries out record.

Particularly, mobile terminal is for current catalogue to be scanned, if judge in step s 102, the timestamp of this catalogue found out from scanning record stabs different from the current time of this catalogue read in step S101, then in this step, the current time of this catalogue stamp is replaced the timestamp of this catalogue recorded in scanning record, and this catalogue is scanned, the information of this catalogue obtained by present scan carries out record.

Or, mobile terminal is for current catalogue to be scanned, from scanning record, the timestamp of this catalogue is not found if judge in step s 102, then in this step, the current time of this catalogue read in step S101 stamp is deposited in scanning record, and this catalogue is scanned, the information of this catalogue obtained by present scan carries out record.

Based on the scan method of the storage space of above-mentioned mobile terminal, the embodiment of the present invention additionally provides a kind of being arranged in mobile terminal the scanister that storage space scans, the block schematic illustration of its inner structure as shown in Figure 2, comprising: scan module 201 and search comparing module 202.

When scan module 201 is for scanning storage space, read the current time stamp of current catalogue to be scanned; Preferably, when scan module 201 pairs of storage spaces scan, determine the quantity of the file under current catalogue to be scanned, when the quantity of the file under this catalogue exceedes setting threshold value, read the current time stamp of this catalogue; And notice is searched in output.

And, if scan module 201 is consistent for the comparative result received, then, after determining that this catalogue is bottom catalogue, skip the scanning to this catalogue, and the information of this catalogue will obtained in last scan process, the information as this catalogue obtained in present scan process carries out record; Preferably, scan module 201 is also after the comparative result of reception is consistent, if determine, this catalogue is not bottom catalogue, the current time stamp of each sub-directory under this catalogue of continuation acquisition, and searches notice for each sub-directory output; Afterwards, according to the comparative result returned for each sub-directory, determine the scanning of whether skipping corresponding sub directory: for each sub-directory, receiving comparative result that this sub-directory returns for after consistent, if determine, this sub-directory is bottom catalogue, then skip the scanning to this sub-directory, and the information of this sub-directory will obtained in last scan process, the information as this sub-directory obtained in present scan process carries out record.

Search comparing module 202 for receive that scan module 201 exports search notice after, from scanning record, find out the timestamp of current catalogue to be scanned, the timestamp that the timestamp found out and scan module 202 read compared; And return comparative result.

Further, search comparing module 202 also for after receiving and searching notice, for current catalogue to be scanned, if do not find the timestamp of this catalogue in scanning record, then the current time of this catalogue stamp is deposited in scanning record, and exports no record notice; Or, after receiving and searching notice, for current catalogue to be scanned, the timestamp found out if judge stabs different from the current time of this catalogue, then the current time of this catalogue stamp is replaced the timestamp of this catalogue recorded in scanning record, and export inconsistent comparative result.

Scan module 201 is also for after receiving the no record notice or inconsistent comparative result of searching comparing module 202 output, and scan current catalogue to be scanned, the information of this catalogue obtained by present scan carries out record.

More preferably, in the scanning record of the embodiment of the present invention, the corresponding catalogue recorded, can also record the routing information of this catalogue, scanning strategy; In addition, in scanning record, the corresponding catalogue recorded can record the type of the file in the type of this catalogue and this catalogue; Based on this, the embodiment of the present invention additionally provides a kind of scan method accelerating storage space:

Mobile terminal, in the process scanned storage space, obtains the routing information of current catalogue to be scanned; Routing information according to this catalogue searches corresponding scanning strategy in scanning record; The scanning result of this catalogue is determined according to the scanning strategy found.

Wherein, the scanning strategy of catalogue can comprise: resolve total description document, file size mean value, skip scanning etc.

When finding the scanning strategy corresponding with the routing information of current catalogue to be scanned for resolving total description document in scanning record, can according to the size of each file in this catalogue recorded in total description document, calculate the size of this catalogue, scanning result as this catalogue carries out record, thus not be used in this scanning process this catalogue is scanned, accelerate sweep velocity.

When scanning that in record to find the scanning strategy corresponding with the routing information of current catalogue to be scanned be file size mean value, after the sum of file under this catalogue can be obtained, the sum calculating acquisition and the product of file size mean value found, scanning result as this catalogue carries out record, thus not be used in this scanning process this catalogue is scanned, accelerate sweep velocity.

When finding the scanning strategy corresponding with the routing information of current catalogue to be scanned for skipping scanning in scanning record, then skip the scanning to this catalogue, and the scanning result of this catalogue that last scan is obtained, the scanning result as this catalogue carries out record.

Preferably, in scanning record, corresponding scanning strategy is that the catalogue skipping scanning can comprise: system directory, size surpass the catalogue of capping or deposit the catalogue etc. of installation kit file.Installation kit file can be specifically the file of expansion APK (AndroidPacKage, Android installation kit) by name.

More preferably, after mobile terminal obtains the scanning result of current catalogue to be scanned, if determine, the quantity of documents under this catalogue exceedes setting threshold value, and the variance of the size of each file is in setting range, then calculate the file size mean value of this catalogue, and using the file size mean value that the calculates scanning strategy as this catalogue, to should catalogue be updated in scanning record.

Based on the scan method of above-mentioned acceleration storage space, in mobile terminal as shown in Figure 2, the scanister of storage space also has following function:

More excellent, in order to reduce the operation of mobile phone users, present invention also offers an a kind of key scanning method of cleaning data of storage space, as shown in Figure 3 a, its flow process specifically can comprise the steps:

S301: after receiving scan instruction, carries out the cleaning data scanning of internal memory, nonvolatile storage space simultaneously.

Particularly, before carrying out cleaning data scanning, user can send scan instruction to mobile terminal.Such as, by clicking the cleaning data scanning button preset in the display screen of mobile terminal, or the preassembled software supporting a key scanning cleaning of cleaning data can be opened, carrying out the transmission of trigger sweep instruction.Mobile terminal carries out the cleaning data scanning of internal memory, nonvolatile storage space after receiving the scan instruction of user's transmission simultaneously.

In this step, the cleaning data scanning of internal memory, nonvolatile storage space specifically can be performed by same process, also can be performed respectively by two processes.Such as, the cleaning data of internal memory can be performed by the internal memory scan procedure preset; The cleaning data scanning of nonvolatile storage space can be performed by nonvolatile storage space scan procedure.In practical application, no matter the cleaning data scanning of internal memory, nonvolatile storage space is performed by a process or two processes, and internal memory and nonvolatile storage space are separately scanning, and internal memory can start a thread and scan; Nonvolatile storage space can distribute thread according to the state of mobile terminal.Such as, on the mobile terminal of CPU multinuclear, scanning thread can be distributed according to CPU and check figure, distribute at most the scanning that 4 threads carry out nonvolatile storage space.

In practical application, in the process of scanning cleaning data, can by the relevant information of the catalogue of Current Scan (such as, the information such as path, bag name) with to download from cloud server in advance or the information of catalogue the local Clean Up Database stored is mated, the information such as Prune Policies and generic corresponding to the catalogue matched, identify the catalogue of Current Scan for cleaning data, and this cleaning data generic can be determined further, and for clearing up the Prune Policies of these cleaning data.Further, cloud server regularly can carry out renewal upgrading to the Clean Up Database of this locality, upgrades in time to the Prune Policies etc. of the catalogue recorded in Clean Up Database and correspondence.

Wherein, the Prune Policies recorded in Clean Up Database can comprise several as follows:

Clear up completely, by this catalogue, and all sub-directories in this catalogue and file all carry out cleaning and delete.

Validity is cleared up, and namely to the file exceeding effective duration in this catalogue, namely stale file carries out cleaning deletion.

Careful cleaning, namely to user point out perform cleaning risk and receive user determination cleaning instruction after, cleaning is chosen to all sub-directories in this catalogue and file.

Part cleaning, namely carries out cleaning to the catalogue or file that are designated suggestion cleaning in this catalogue and deletes; To the catalogue or the file that are designated careful cleaning in this catalogue, after the instruction of determination cleaning receiving user, carry out cleaning delete; To the catalogue or the file that are not designated suggestion cleaning or careful cleaning in this catalogue, do not carry out choosing cleaning.

Wherein, the generic of the cleaning data recorded in Clean Up Database specifically can comprise: internal storage data, data cached, system disk junk data, ad data, installation kit data, unloading residual data, large file etc.

S302: periodically according to the progress of the cleaning data scanning of internal memory, and the progress of the cleaning data scanning of nonvolatile storage space, calculate overall progress.

Particularly, can in the scanning process of cleaning data, according to following formula 1 calculate i-th cycle arrive time overall progress J _i:

J _i=j _ciw _c+ j _fiw _f(formula 1)

In formula, j _cibe the progress of the cleaning data scanning of internal memory during i-th cycle arrival, j _fiit is the progress of the cleaning data scanning of nonvolatile storage space during i-th cycle arrival; w _cfor internal memory scanning accounts for the accounting weight of overall progress, w _ffor nonvolatile storage space scanning accounts for the accounting weight of overall progress; I is natural number.

Wherein, internal memory scanning accounts for the accounting weight that the accounting weight of overall progress and nonvolatile storage space scanning accounts for overall progress and presets.Such as, if after the cleaning data scanning of internal memory completes, its progress accounts for 50% of overall progress; Correspondingly, after the cleaning data scanning of nonvolatile storage space, its progress accounts for 50% of overall progress, then the accounting weight setting that internal memory scanning can be accounted for overall progress is 0.5, is 0.5 by the accounting weight setting that nonvolatile storage space scanning accounts for overall progress.Like this, the progress of the cleaning data of the internal memory of Current Scan be 50%, the progress of the cleaning data of nonvolatile storage space be 20% time, according to above-mentioned formula 1 and the accounting weight that presets, calculating overall progress is 35%.

Certainly, in practical application, method for distinguishing also can be adopted to carry out calculated population progress, such as, according to the progress of the cleaning data scanning of the progress of the cleaning data scanning of internal memory, nonvolatile storage space, internal memory and nonvolatile storage space size separately, calculated population progress can be carried out.

S303: on display interface, carries out the progress display of progress announcer according to overall progress.

In this step, on display interface, according to the overall progress that step S302 periodically calculates, periodically progress display can be carried out by progress bar as shown in Figure 3 b.

Certainly, in practical application, progress announcer, except being specially progress bar, can also be specially circular progress percentage display.

S304: on display interface, according in the cleaning data scanning process of nonvolatile storage space, the size of the current cleaning data scanned, the color of progress displaying announcer.

In the embodiment of the present invention, step S303, step S304 do not have execution sequence successively, and namely step S304 can perform prior to step S303 or with step S303 simultaneously.

More excellent, the embodiment of the present invention also provides two kinds of methods of clearing up cache file, and wherein a kind of schematic flow sheet clearing up the method method of cache file, as described in Figure 7, comprises the following steps:

S701, obtains cache information and the original information corresponding with cache information.

The method of this method is applicable to the cleaning of intelligent terminal cache file, the especially cleaning of cache file in mobile terminal.First intelligent terminal obtains cache information and original information, below for the file of particular type, is described cache file information and original information.

A. application program

Application program, in operation or installation process, can produce corresponding cache file, make application program when follow-up operation, not need to resolve again, thus improves the travelling speed of application program.

The application scenarios of this method method is, when the improper unloading of application program, its some cache file corresponding still exists, due to None-identified cleaning, make these cache files take spatial cache, if this type of cache file is too much always, the performance of intelligent terminal can be affected, reduce Consumer's Experience.

Therefore, the identification for application program invalid cache file is cleared up, and cache information is virtual machine buffer memory bag name, i.e. the bag name of virtual machine cache file, and original information is installation file bag name, is generally the bag name of each file in installation file list.

B. picture

The buffer memory of picture is thumbnail, can realize the fast browsing to picture by thumbnail.

The application scenarios of this method method is, when former picture does not exist, if its corresponding thumbnail is not cleared up in time, can take spatial cache, affect the performance of intelligent terminal.

Therefore, identification for picture invalid cache file is cleared up, cache information is thumbnail information, be specially the information in thumbnails table in database, original information is be the former figure information of mapping relations with thumbnail information, the information namely in database in picture table (image table).

S702, mates cache information with original information.

In conjunction with the analysis of above-mentioned A, B two kinds of scenes, can be two objects that there is corresponding relation by cache information and original comprehension of information, in theory, cache information and original information should keep corresponding relation each other, if one cache information cannot be corresponding with all original information, just this cache information can be considered as object for clearance in this case.

Identification for application program invalid cache file is cleared up, virtual machine buffer memory Bao Mingyu installation file bag name is mated, when the file bag name of virtual machine buffer memory Bao Mingzhong is when the coupling of installation file Bao Mingzhong is less than file bag name corresponding thereto, this cache file corresponding to file bag name is invalid cache file.

Be specially, bag name in Bao Mingyu in .dex file installation file list is mated, when the file bag name in .dex file can not find file bag name corresponding thereto in installation file list, illustrate that this file corresponding to file bag name is not in installment state, therefore, the cache file of this file bag name correspondence is invalid cache file.

Identification for picture invalid cache file is cleared up, thumbnail information is mated with former figure information, when the fileinfo in thumbnail information mates less than fileinfo corresponding thereto in former figure information, the cache file that this fileinfo is corresponding is invalid cache file.

Be specially, information in information in thumbnails table being shown with image is mated, and when the ID in thumbnails table can not find ID corresponding thereto in image table, illustrates that the picture file corresponding to this ID is deleted, therefore, the thumbnail that this ID is corresponding is invalid thumbnail.

S703, when the fileinfo in cache information mates less than fileinfo corresponding thereto in original information, the cache file that cleaning fileinfo is corresponding.

After identifying invalid cache file, invalid cache file is cleared up.

The above, the method for this method cleaning cache file, can carry out identification cleaning to the invalid cache file in buffer memory, need a key cleaning or select cleaning, improve Consumer's Experience effect when avoiding user to clear up invalid cache.

Refer to Fig. 8, Fig. 8 is the schematic flow sheet that the present invention clears up the other method of cache file, as shown in Figure 8, comprises the following steps:

S801, obtains cache information and the original information corresponding with cache information.

S802, mates cache information with original information.

S803, when the fileinfo in cache information mates less than fileinfo corresponding thereto in original information, it is invalid to be designated by cache file corresponding for fileinfo.

S804, after cache information and original information matches complete, cleaning is designated invalid cache file.

Wherein, the step S701 in method shown in step S801, S802 and Fig. 7, S702 are identical, do not repeat them here.

In the method, the invalid cache file identified is identified, after coupling completes, be designated invalid cache file clear up all.

It is pointed out that intelligent terminal can according to user instruction or clocked flip setting up procedure S801, after coupling completes, intelligent terminal can be cleared up for invalid cache file according to user instruction or automatic benchmarking's knowledge.
