/* 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.
