    /* This is a very simple format created by a German application called CisCopy, aka CCOPY.EXE, with extension .DCF.
     * First byte indicates the floppy type, limited to standard formats.
     * Indeed if the floppy is not DOS formatted, user must choose from the list of supported formats manually.
     * Next 80 bytes (for 5.25" DD disks) or 160 bytes (for 5.25" HD and 3.5" disks) indicate if a track has been copied
     * or not.
     * It offers three copy methods:
     * a) All, copies all tracks
     * b) FAT, copies all tracks which contain sectors marked as sued by FAT
     * c) "Belelung" similarly to FAT. On some disk tests FAT cuts data, while belelung does not.
     * Finally, next byte indicates compression:
     * 0) No compression
     * 1) Normal compression, algorithm unknown
     * 2) High compression, algorithm unknown
     * Then the data for whole tracks follow.
