Decrease in the write speed is prevented even when overwriting the entire file. When a NAS apparatus receives a file size change request from a computer as an access request source for changing the size of a file, the NAS apparatus creates a new file related to the file in a file system with a processing performance that is higher than a file system containing the file as an entity of that file, associates the new file and the foregoing file, deletes the file on the condition that the new file and the file has been associated, and executes data write processing of writing data into the new file on the condition of subsequently receiving a data write request from the access request source for writing data into the file. |
