1. 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 it is determined that 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 as it is when it is determined that 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 as it is; 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.

8. A file management method enabling a file system capable of treating only a file with standard file name following the existing file denomination rule to allow for use of an arbitrary file name separately assigned to the file, and the file management method comprising the steps of:
-
managing a file name correspondence table 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;
switching between an arbitrary file name mode allowing for use of an arbitrary file name and a standard file name mode not allowing for use of an arbitrary file name;
determining, when an external application displays a file name of a file stored in a storage medium in the arbitrary file name mode, whether an arbitrary file name has been assigned to the file or not based on the file name correspondence table, converting a standard file name acquired from the file system to the arbitrary file name based on the file name correspondence table and displaying the arbitrary file name, or displaying the standard file name acquired from the file system as it is when any arbitrary file name has been assigned to the file; and
giving an instruction for accessing an access target file to the file system, when an external application accesses a file stored in the storage medium in the arbitrary file name mode, by using, when the access target file is specified with an arbitrary file name, a standard file name generated by converting the arbitrary file name based on the file name correspondence table, and by using, when the access target file is specified with a standard file name, the standard file name as it is.

9. A program enabling a file system capable of treating only a file with standard file name following the existing file denomination rule to allow for use of an arbitrary file name separately assigned to the file, and the program enables a computer to function as:
-
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 it is determined that 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 as it is when it is determined that an arbitrary file name is not assigned to the file;
a file access control section that gives an instruction for access 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 as it is; 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.
