1. An audio-video system comprising:

  • an audio-video processing section operatively coupled to a recording medium;

    the recording medium having a preinstalled media area configured to contain an original file and a file for restoration, the original file is edited or deleted via user operation, the file for restoration (1) differing from the original file in at least one of a filename and an extension and (2) being a hidden file that cannot be edited or deleted via user operation;

    a reproducibility determining section operatively coupled to the audio-video processing section and configured to determine (a) whether the original file has been deleted and (b) whether the original file is corrupted; and

    a file restoring processor operatively coupled to the audio-video processing section configured to restore the original file to a reproducible state when the reproducibility determining section determines that either the original file has been deleted or is not capable of being reproduced due to corruption, wherein the file restoring processor includes a display section for informing a user that the reproduction of the original file is impossible when the reproducibility determining section determines that the original file is not capable of being reproduced, and the file restoring processor modifies at least one of the filename and the extension of the copied file for restoration when an instruction to restore the file is received from the user in response to the information provided by the display section, and;

    wherein the original file is restored by copying the file for restoration and modifying at least one of the filename and the extension of the copied file for restoration to be the same as that of the original file, while maintaining the file for restoration in an unaltered state for use during subsequent file restorations.
