Abstract
Since no access history is generated for when a file update which makes use of a copy and paste function is performed, it is difficult to detect the file that served as the reference source during the update. Hence, the present invention is provided to manage a client access history for each file that is stored in a storage device, and detect a file, which has been accessed between a time when a corresponding user logs into the storage device and a time when an updated file is updated based on information of the access history, as the reference source for the updated file.
