ABSTRACT:
In the method of controlling a file system driver of an electronic computer and the program for the method and further the storage medium containing the program according to the present invention, access to a file stored in a storage device of the electronic computer is controlled in a kernel mode.When a specific file in a file system of an electronic computer (11) is accessed from an application program (4), the access is received in a kernel mode (8) of an OS (3). Then, an access control database (36) comprising filenames in the file system and access methods is referenced to judge whether or not the access to the specific file conforms to conditions prescribed in the access control database (36). If the access to the specific file does not conform to the conditions, the access is canceled.
