Abstract
A method of managing files of an interchangeable storage medium having a RAM area defining an independent RAM section and a ROM area defining an independent ROM section, each section having a file management area for storing file management data and a file area for storing files. The method includes reading file management information out of a file management area of the ROM section in response to a request for establishing a section in which the RAM area and the ROM area are mixed, converting the file management information of the ROM section to file management information of the mixed RAM-ROM section, writing the file management information of the mixed RAM-ROM section in a file management area of the mixed section, and managing ROM files and RAM files as files of the mixed section.
