In another specific embodiment of the invention, when above-mentioned file management request is file modification request, then need
File destination is modified based on the request of file application layer, that is to say, that corresponding current user operation is to deposit in the first kind
Stored file is modified in storage area domain.
Further, above-mentioned the step of being requested according to file management, being operated to file destination, can specifically execute
Are as follows:
During modifying file destination, the size of memory space shared by file destination reality is obtained；
In the case that the size of the memory space shared by file destination reality exceeds the second given threshold, it is based on file destination
Type determine target processing mode, and the modification to file destination is completed based on target processing mode, the second given threshold with
The type of file destination is corresponding.
It is understood that, it is contemplated that the storage for storing the first kind storage region of the higher file of importance value is empty
Between finiteness need to carry out the size of memory space shared by file destination reality quasi- during modifying file destination
Really detection can be in the case where exceeding corresponding second given threshold with the size of the memory space shared by file destination reality
According to the difference of the type of file destination, different processing modes is respectively adopted to complete the modification to file destination；In this way, logical
It crosses and matches corresponding memory space processing mode respectively for different types of file, can satisfy the modification of different types of file
Demand, to achieve the effect that efficient file management.
Specifically, it in the case where the type of file destination is the above-mentioned first kind, needs to check during modification
File destination reality shared by memory space size, if beyond marking off from target storage domain for storing the first kind
Whether the size (i.e. the second given threshold) of the residual memory space of first subregion of the file of type determines the first subregion
There is sufficient residual memory space for storing modified file destination.Further, if without departing from can be in the target
The modification to file destination is completed in storage region, if exceeding, can prompt to carry out the memory space of the first subregion clear
Reason is to vacate enough memory spaces, for storing modified file destination.
In addition, needing to check during modification in the case where the type of file destination is above-mentioned Second Type
The size of memory space shared by file destination reality, if there is the second given threshold beyond the type matching for file destination
Memory space size, that is, determining whether the size of memory space shared by modified file destination reality has exceeded can be from
Target storage domain for its memory space marked off the upper limit (i.e. the second given threshold).Further, if without departing from can
To complete the modification to file destination in the target storage domain, if exceeding, can prompt to modify the second given threshold
For the value bigger than the size of memory space shared by modified file destination reality, or can prompt to occupied and mesh
The corresponding memory space of type of mark file is cleared up, to vacate enough memory spaces for storing modified target text
Part, or abandon modifying the file destination in target storage domain, and be transferred to Second Type storage region and carry out file destination
