File format
Signature
There is no signature, so the only known way of detecting whether a file is in this format or not is to carefully parse the header and FAT and ensure the values make sense, e.g. the FAT length is less than all the file offsets, no file offset goes past the end of the file, all filenames end with a terminating NULL, etc.
