Part is deleted respectively, compressed or is retained.
As shown in figure 4, in one embodiment provided by the invention, step S30: described according to the big of the weight sum
It is small, retain, compress or delete corresponding file in the caching, comprising:
S31 judges the weight and whether is more than or equal to the second default value.
S32A, if the weight and be more than or equal to second default value, retain the weight and be more than or equal to institute
State the file of the second default value.
Wherein, the second default value is set according to actual needs, as needed preset time number in caching
File more than or equal to 10 times retains, then can set 3 for the second default value；If desired preset time indegree in caching
File more than or equal to 15 times retains, then can set 5 for the second default value, the embodiment of the present invention is not specifically limited.
S32B is obtained if the weight and being less than second default value and described is less than second default value
The memory capacity of file.
Wherein, step S32B is the step arranged side by side of step S32A, whether is more than or equal in the frequency of use for judging file
After two default values, if the frequency of use of file is more than or equal to second default value, it is big to retain the frequency of use
In the file for being equal to second default value；If the frequency of use of the file is less than second default value, obtain
The memory capacity less than the second default value file.
In embodiments of the present invention, the file for frequency of use less than the second default value then needs further really
The operation of progress required for the fixed file less than the second default value, that is, obtain depositing less than the second default value file in caching
Store up capacity, that is, occupy spatial cache capacity, in order in the next steps according to occupy spatial cache capacity, in caching
File selectively deleted or compressed.
S33B is compressed or is deleted to the file for being less than second default value according to the memory capacity of the file
It removes.
For the embodiment of the present invention, after whether the frequency of use for judging file is more than or equal to the second default value, if
The frequency of use of file is more than or equal to second default value, then it is preset more than or equal to described second to retain the frequency of use
The file of numerical value；If the frequency of use of the file is less than second default value, obtain described pre- less than described second
The memory capacity of setting value file, and the file for being less than second default value is compressed according to the memory capacity of file
Or delete, the frequency so as to effectively be used according to file in caching carries out compression or delete operation, realizes targeted
File in caching is handled, the effective percentage of file storage in caching is improved.
In one embodiment provided by the invention, step S33B: the memory capacity according to the file is to being less than
The file of second default value is compressed or is deleted, and is specifically included: obtain the file memory capacity and the text
Frequency of use of the part within the scope of preset time；Third default value is greater than to the memory capacity and within the scope of preset time
Frequency of use deleted less than the file of the 4th default value；Third preset number is less than or equal to the memory capacity
The file that value and the frequency of use within the scope of preset time are greater than the 4th default value is compressed.Wherein, third is pre-
Setting value is set according to actual needs, the biggish file of memory space is occupied in caching for determining, the third is pre-
Setting value is specifically as follows 10M, 20M, 30M etc., and the embodiment of the present invention is not specifically limited.4th default value is for relatively more single
The frequency of use of file in position time caching, and the 4th default value is less than the second default value.For example, third default value is
30M, the 4th default value are to use 5 times per minute；Then it can be greater than 30M and access times per minute to memory capacity in this example
File less than 5 is deleted, and is less than or equal to 30M to memory capacity and file of the access times per minute more than or equal to 5 carries out
Compression occupies lesser memory space with the file that this guarantees to store in the buffer.
For the embodiment of the present invention, although the program being of little use, if its cache file generated is smaller, no
It can preferentially selection delete, but delete those bigger cachings being also of little use.Reduce file selecting different compression ratios
Also the speed of compression and the relationship of compression ratio are contemplated that when volume: when bigger compression ratio needs more long compression time and decompression
Between.
In one embodiment provided by the invention, after being compressed to the file in caching, in order to guarantee to cache
The storage validity of middle compressed file, the method also includes: obtain compressed file in the caching makes in preset time
Use frequency；If frequency of use of the compressed file in preset time is greater than predetermined frequency, the compressed file is carried out
Decompression, which contracts, to be stored in the caching；If frequency of use of the compressed file in preset time is less than or equal to predetermined frequency,
Then the file is deleted from the caching.Wherein, predetermined frequency can be set according to actual needs, such as by preset frequency
Rate is arranged to the number that file is frequently used in caching, and the specific predetermined frequency can be the second above-mentioned default value,
I.e. when the color files in caching in preset time frequency of use be greater than the second default value when, need to the compressed file into
Row decompression, in order to which program quickly obtains this document from caching；And for often not made in preset time in caching
Compressed file then needs from caching directly to delete the compressed file, to reduce the memory space occupied in caching.
It should be noted that if frequency of use of the compressed file in preset time is less than or equal to predetermined frequency, then also need
Further to judge that frequency of use of the compressed file in preset time, will compression if being less than whether less than the first default value
File is directly deleted from caching；If frequency of use of the compressed file in preset time is preset between predetermined frequency and first
Between numerical value, then retain the storage of the compressed file in the buffer.
In one embodiment provided by the invention, in order to improve the efficiency that program obtains file in caching, to caching
The enough situations in middle space are to the file compressed to caching unzips it.Even it is described use memory capacity and
In the caching can storage file total capacity accounting be lower than the second preset accounting, then in the caching compressed file carry out
Decompression.Wherein, it is set according to actual needs when the second preset accounting, if the second preset accounting is 20%, 30%
Deng the embodiment of the present invention is not specifically limited.
