1. A management device comprising:
at least one memory storing program instructions; and
at least one processor configured to execute the instructions stored in the memory to:
monitor whether a file has been saved in a storage area managed by a file server;
determine, when a file saved in the storage area is detected, whether identification information on a user who has saved the file matches identification information on a specific user; and
change, when the identification information on the user who has saved the file matches the identification information on the specific user, an access privilege of the file,
wherein in a case where the user has moved the file from a first storage area to a second storage area in the storage area, the access privilege of the file is changed from an access privilege designated for the first storage area to an access privilege designated for the second storage area when it is determined that the identification information on the user matches the identification information on the specific user, and the access privilege designated for the first storage area is maintained as the access privilege of the file when it is determined that the identification information on the user does not match the identification information on the specific user.
