摘要： It is possible for an information processing device to read or write a large amount of contents-related information more quickly if the device has a relatively small processing capacity. The file format identifier information and the block identifier information that correspond to contents-related information are identified in Step S11 and it is determined in Step S17 if the file format version information read out from the file identified by the file format identifier information and the predefined file format version information agree with each other or not. If it is determined that the two pieces of file format version information agree with each other, the related information is read out from the block identified by the block identifier information of the identified file according to the block position information of the identified file in Step S22.

摘要： The present invention provides a configuration that verifies erased contents at a check-out destination efficiently and properly. A portable device or other apparatus at a contents check-out destination retains an erased contents management file, which registers contents identification information corresponding to check-out contents erased in the portable device or the like. A personal computer at a contents check-out source performs an erased contents verification process in accordance with the information registered in the erased contents management file and performs an update process (check-in process) on a check-out counter for contents whose erasure has been verified. Even if a large amount of check-out contents exists, the present invention can efficiently perform an erased contents verification process and check-in process.
