Subsequent descriptions for implement the application better embodiment, so it is described description be for the purpose of the rule for illustrating the application,
It is not limited to scope of the present application.The protection domain of the application is when subject to appended claims institute defender.
In the application, it will need to make equipment cache new cache file user, but during memory space inadequate, show one
List for clearance, so as to guide user to delete a part of first cache file, to reach the effect of cleaning memory space；To protect
Demonstrate,proving new cache file can smoothly be saved among the built-in storage of equipment.It is shown in Figure 1, delay for herein described equipment
Deposit the method for sorting of file.Method comprises the following steps described in the present embodiment：
Step 101, specify when equipment and treat cache file, then treats whether the volume of cache file is worked as more than equipment described in judgement
Preceding residual memory space；If the volume for treating cache file is more than the residual memory space, cache file will be treated
Volume and the difference of the residual memory space are as supplement space.
In the present embodiment, it is assumed that user is used as by the file A that equipment specifies a volume to be 1.5GB treats cache file.
Inevitable, need to leave the memory space more than 1.5GB in equipment, it is described to treat that cache file be completed to cache, be otherwise
Illustrate memory space inadequate.
After specifying and treating cache file, it is 0.9GB to read current device residual memory space, then treats cache file
Volume is more than the current residual memory space of equipment, illustrates current memory space deficiency, can not complete to treat that cache file A's is slow
Deposit.At this time, the volume and difference 1.5-0.9=0.6GB of the residual memory space that will treat cache file, as supplement space.Institute
State supplement space to also mean that, it is necessary to clean out at least space of 0.6GB in equipment storage, can realize and treat caching text
The caching of part A.
Step 102, according to default screening rule, the one or more cache files cached of screening are as text for clearance
Part；The volume of the file for clearance is not less than the supplement space；The file for clearance is added into list for clearance, and will
The list display for clearance.
When device memory is insufficient, buffered a large amount of cache files before general remark equipment, and without and
When arrangement or deletion, so as to occupy excessive space.In the present embodiment, in order to actively guide user in this case
The arrangement of memory space is completed, so will automatically be filtered out from the cache file previously cached one or more as treating
File is cleared up, for the deletion of user's selectivity to clean out memory space.Foregoing to have calculated, supplement space is 0.6GB, so sieve
The volume for the file for clearance selected also needs to be not less than the 0.6GB, so after file for clearance is deleted, can solve to deposit
The problem of storing up insufficient space.
The screening of file for clearance, is to be based on screening rule, is to sieve as far as possible in the basic principle of the screening rule
Cache file that user no longer needs is selected as file for clearance.Refer to following several ways：
A, according to the time sequencing for completing caching, screening is initially completed the cache file that the one or more of caching has cached
As file for clearance.
I.e. sequentially in time, it is believed that complete caching time it is more early, preserve it is more long in a device, most possibly no longer by
User needs, and can be deleted with prioritizing selection.
B, the time sequencing browsed according to completion, screening finally complete the cache file that the one or more browsed has cached
As file for clearance.
I.e. also according to time sequencing, it is believed that cache file browsed in the recent period, since having completed to browse, then most possibly
No longer needed by user, so prioritizing selection is deleted.
C, the minimum one or more cache files cached of broadcasting frequency are filtered out as file for clearance.
Think, browse that frequency is low this means that the desirability of user is low, can preferentially delete.
D, the maximum one or more cache files cached of volume are filtered out as file for clearance.
Which filters out the big caching text of occupied space as far as possible no longer from the angle of user demand degree
Part is preferentially deleted, to clean out more spaces as far as possible.
Any of the above mode can also be combined with each other in any way separately as the screening rule in the present embodiment
As the screening rule in the present embodiment.In addition, other similar screening modes, can also serve as screening rule and are incorporated in this
Among the overall technical architecture of embodiment.In short, the content in the present embodiment for screening rule does not limit specifically.
Assuming that in the present embodiment, a modes are selected then to filter out B, C, the D tri- for completing caching earliest as screening rule
Cache file, the volume of three are respectively 0.2GB, 0.3GB and 0.5GB, summation 1GB, more than the supplement space, then by this
Three is added among a list for clearance as file for clearance.
Then, the list for clearance is shown to user, user can learn each file for clearance for filtering out
The relevant information such as filename, file size, and decide whether to delete file for clearance.User can be directly to described for clearance
List input instruction, file for clearance therein is deleted.
It is so-called in the present embodiment actively to guide user to clear up memory space, substantially namely automatically one is shown to user
A list for clearance so that user can avoid manual lookup and transfer caching text directly to the list operation for clearance
The catalogue of part；It also prevent user to forget to clear up memory space, or do not know how that the situation of cleaning memory space occurs.
Preferably, can also include here in this step：
Step 102a, extended instruction is generated when equipment is directed to list for clearance, then again according to default screening rule, sieve
The one or more cache files cached of choosing are as file for clearance；The file for clearance is added into list for clearance.
That is, if user is not desired to delete the file for clearance filtered out first, or user is intended merely to delete it
Middle part file for clearance, and the volume of this part file for clearance is less than supplement space, user can also pass through extended instruction
More files for clearance are obtained, then are artificially selected.
Such as in the present embodiment, in file B, C, D for clearance for filtering out, user wishes to retain file D for clearance.But treat
It is 0.5GB to clear up the sum of volume of file B and C, less than supplement space.Then user will be referred to by equipment one extension of input at this time
Order, and then for clearance file new according to the screening of default screening rule again, i.e., it is 0.9GB's to filter out volume again
File E for clearance, is added to list for clearance.
Described to screen file for clearance again according to default screening rule, its principle is for clearance with being screened in step 102
File is identical, the narration being not repeated herein.
Step 103, when equipment for list for clearance generation delete instruction, then according to it is described delete instruction delete it is for clearance
File for clearance in list.
User can taking human as selection delete those files for clearance in list for clearance, directly to list for clearance into
Row operation, input delete instruction, delete any one or more files for clearance in list for clearance.In the present embodiment, use
Family, which can operate, only deletes file E for clearance, can also all delete file B, C, E for clearance, can realize cleaning foot
The purpose of enough memory spaces.
Step 104, start to cache and appointed treat cache file.
After cleaning obtains the memory space not less than supplement space size, you can start to cache and appointed treat caching text
Part.
