Claim:
A file management apparatus configured to enable a file system capable of treating only a file with a standard file name following the existing file denomination rule to allow for use of an arbitrary file name separately assigned to the file, the file name management apparatus comprising: a table management section that manages a file name correspondence table in which correspondence between standard file names assigned to one or more files stored in a storage medium and arbitrary file names separately assigned to the files is described; a file name display control section that determines, when an external application displays a file name of a file stored in a storage medium, whether an arbitrary file name is assigned to the file based on the file name correspondence table, converts, when an arbitrary file name is assigned to the file, a standard file name acquired from the file system to the arbitrary file name based on the file name correspondence table and displays the arbitrary file name, or displays the standard file name acquired from the file system when an arbitrary file name is not assigned to the file; a file access control section that gives an instruction for accessing to an access target file to the file system by using, when an external application accesses a file store in a storage medium and specifies an access target file with an arbitrary file name, a standard file name converted from the arbitrary file name based on the file name correspondence table, or by using, when the access target file is specified with a standard file name, the standard file name; and a mode switching section that switches an operating mode between the arbitrary file name mode in which an arbitrary file name is acknowledged and the standard file name mode in which an arbitrary file name is not acknowledged by turning ON or OFF functions of the file name display control section and the file access control section.
