Header
| Start | Length | Typical value | Description |
|---|---|---|---|
| 0 | 4 | 'VFF' and 0x20 | 4-byte magic |
| 4 | 2 | feff | Byte order mark (in this case, big endian) |
| 6 | 2 | 0100 | ? (2's complement of previous field ?) |
| 8 | 4 | 01400000 | Total file size |
| 12 | 2 | 0020 | Offset to start of first FAT |
| 14 | 18 | zeroes | padding |
There are two FATs, one located at offset 0x20, the other at 0x14020. They should generally be identical.
The root directory begins at 0x28020; see http://en.wikipedia.org/wiki/File_Allocation_Table#Directory_table for the format.
Clusters seem to be 0x1020 bytes each (!?!)
