ABSTRACT:
An information processing apparatus for generating directory information to manage a file using directories, includes a first generator for generating first directory information including first identification information to identify one of the directories and second identification information indicative of which directory the one of the directories belongs to. A recorder records the first directory information generated by the first generator on a recording medium and a reader reads the first directory information recorded on the recording medium. A second generator generates second directory information including the first and second identification information and third identification information indicative of which directory belongs to the one of the directories, on the basis of the first and second identification information of the first directory information read by the reader. The first identification information identifies one directory or one file, and the second generator generates the second directory information which includes the third directory information when the first identification information indicates the directory, while the second generator generates the second directory information which does not include the third identification information when the first identification information indicates the file.
