Facilitate follow-up data modification operation.
Pipe below, to disclosure offer taking data modification operation respectively data write operation data deletion action as a example
The method of reason file system quota is described in detail.
Data modification operation is data write operation
Fig. 3 is the flow chart of a kind of method of management file system quota according to another exemplary embodiment.As
Shown in Fig. 3, the method can include following step：
In step 301, when the data modification operation to file system is detected, obtain this data modification operation and correspond to
Data occupancy.
, with step 101, here is omitted for this step.
In step 302, obtain the ID of execution data modification operation.
When file system is only for unique user, this step can be omitted.
In step 303, by the space usage amount initial value of the corresponding file system of this ID in internal memory and above-mentioned number
It is added according to occupancy, obtain the first value preset, as the space usage amount final value of file system.
Because the space usage amount leading to file system is increased by data write operation, therefore, write in known this data of execution
After the ID of operation, calculate at the beginning of the space usage amount of the corresponding file system of ID executing this data write operation
Value data occupancy sum, obtains the first value preset, as the space usage amount final value of file system.
Further, judge this first value preset with execute this data write operation the corresponding Disk Quotas of ID big
Little.
In step 304, if the first value preset is less than or equal to the corresponding Disk Quotas of this ID in internal memory, will
This data modification operation corresponding data writes file system.
Wherein, the first value preset is less than or equal to the corresponding Disk Quotas of this ID in internal memory, and current residual is described
(the corresponding Disk Quotas of ID executing this data write operation deducts the corresponding file of this ID to storage size
The space usage amount initial value of system) this data write operation corresponding data enough write, therefore, this data modification operation is corresponded to
Data writes file system.
Correspondingly, in step 305, by the space usage amount initial value of the corresponding file system of this ID in internal memory more
It is newly the first value preset.
That is, the above-mentioned space usage amount final value write internal memory by file system, can include：By this use in internal memory
The space usage amount initial value that family identifies corresponding file system is updated to the first value preset.
Wherein, the corresponding of ID, the space usage amount initial value of file system and Disk Quotas that be stored with internal memory is closed
System.
Alternatively, above-mentioned steps 304 can also be：If the first value preset is more than the corresponding magnetic of this ID in internal memory
Disk quota, then terminate data modification operation flow process；The information that display memory space transfinites.Now, no longer execution step 305.
Wherein, the first value preset is more than the corresponding Disk Quotas of this ID in internal memory, illustrates that the storage of current residual is empty
Between size (the corresponding Disk Quotas of ID executing this data write operation deducts the corresponding file system of this ID
Space usage amount initial value) it is not enough to support the write of this data write operation corresponding data, therefore, terminal terminates data modification operation
Flow process.In the case of being somebody's turn to do, in internal memory, the space usage amount initial value of the corresponding file system of this ID keeps constant.
In sum, the method for the management file system quota that the present embodiment provides, when there being new data write, by more
Execute the space usage amount initial value of the corresponding file system of ID of data write operation, it is to avoid this user is marked in new internal memory

Shown in Fig. 4, the method can include following step：
In step 401, when the data modification operation to file system is detected, obtain this data modification operation and correspond to
Data occupancy.
, with step 101, here is omitted for this step.
In step 402, delete the corresponding data of data modification operation.
For this step, it will be understood by those skilled in the art that because data deletion action will lead to the sky of file system
Between usage amount reduce, be not related to the problem that memory space transfinites, therefore, terminal directly executes data deletion action.
In step 403, by the space of the corresponding file system of the ID executing this data deletion action in internal memory
Usage amount initial value deducts above-mentioned data occupancy, obtains the first difference, as the space usage amount final value of file system.
In step 404, the space usage amount initial value of the corresponding file system of this ID in internal memory is updated to
One difference.
This step is used for updating the space of the corresponding file system of ID executing this data modification operation in internal memory
Usage amount initial value.
In sum, the method for the management file system quota that the present embodiment provides, when deleting data, in updating
