S303：Second file is moved to external memory by file-storage device from built-in storage.
When the status information for the second file for judging built-in storage meets first movement condition, then it is assumed that second file is more
It is suitble to be stored in built-in storage.When the status information for judging second file does not meet first movement condition and meets the second shifting
Dynamic condition, then it is assumed that second file can be stored in external memory, and then by second file from the memory of file memory
It is moved in the external memory of file memory and is stored in reservoir.Such as there is a certain size and file when the second file is in
When accessing state infrequently, which is stored in the access speed external memory slow compared with built-in storage by file-storage device
In reservoir, the occupancy to the memory space of built-in storage thus can be reduced, moreover, for the second less text of such file access
Part is then moved in external memory storage, will not often be read, therefore not have too big influence on user experience.And for
Smaller second file of file, is retained in built-in storage, will not the excessive space of committed memory reservoir.
Further, similar to above-mentioned embodiment illustrated in fig. 2, file-storage device can also correspond to the access speed of external memory
It spends and different second is set to set status information.For example, this method further includes in another embodiment：Obtain the outer storage
The access speed of device, and from setting set of state information, obtain the second setting status information corresponding with the access speed；
Whether the status information for judging second file in above-mentioned S302 meets the second mobile condition, including：Described in judgement
It is described whether the relationship between the status information of the second file the second setting status information corresponding with the access speed meets
Second mobile condition；Above-mentioned S303 includes：Second file is moved to and the access speed pair from the built-in storage
The external memory answered.
Wherein, the setting set of state information is included by multiple second setting shapes corresponding from different access speeds respectively
State information, the second setting status information include at least one of the second setting file size and the second setting access times.
In the present embodiment, which is set as different rates grade and corresponds to different set status information,
Wherein, the corresponding access speed of each speed grade can be as shown in upper table one, and set that set of state information includes second sets
Determining status information can be as shown in following table three.

First setting status information of a external memory and the second setting status information, judge the second file in built-in storage relative to
Whether the external memory does not meet first movement condition and meets the second mobile condition, if so, the second file is moved to symbol
In the correspondence external memory for closing the mobile condition.For example, the storage speed of external memory A is 2, then corresponding speed grade is
Class2, first sets file size as 3MB, and first sets access times as 5, and second sets file size as 1MB, and second
Access times are set as 1.The size of the second file in built-in storage is 2MB, and the access times in setting time are 0, then
It determines second file being moved in external memory A from built-in storage.
It is understood that the Provisioning Policy of above-mentioned second setting file size and the second setting access times can be as follows：
External memory speed grade is lower, and access speed is slower, and efficiency is lower when file-storage device accesses file, so the second setting
File size and second setting access times be required for setting it is smaller, and second setting file size and second setting access time
Number is necessarily less than corresponding status information in table two, and to ensure compliance with the second mobile condition when does not meet first movement condition then.
Above-mentioned set information can be according to needing to be modified, and upper table three is an example.
In the present embodiment, file-storage device detects the file status of built-in storage, and is judging that this document state is not inconsistent
