The preset character string may be randomly generated, and the present invention is not limited thereto.
In addition, since the paths mounted on the same target device are unique, a unique first identification code can be generated according to the third identification code and the MD5 value, and then the storage location of data can be accurately determined according to the unique first identification code when data is read.
The execution unit 116 obtains a second identification code corresponding to the file data, and stores a corresponding relationship between the first identification code and the second identification code.
