PROBLEM TO BE SOLVED: To eliminate the need to change the access right by an administrator each time access to a file, etc., is limited by allowing or disallowing access by comparing the current time with the access allowed/disallowed time zones of the file, etc. SOLUTION: The access to the file is allowed or disallowed by comparing the current time with the access allowed/disallowed time zones of the file, etc. This system sets the limit properties (access time limit property) of the access allowed/disallowed time zones by files, folders, and drives on the floppy disk(FD) 11, MO 12, and hard disk(HDD) of a server 10. When the FD 11, MO 12, or HDD 13 is accessed, the OS judges whether or not the access is allowed by the files, folders, and drives according to the access time limit properties.
