Does anyone out there know the format of MS-DOS backup diskettes?
I've figured out the obvious stuff (i.e. that there's a file called
BACKUPID.@@@ on the disk, that that file's 128 bytes long and contains
some representation of the date, that the backup-up files have 128 bytes
set aside at the start (with the original path name starting at the fifth
byte), etc) but am looking for specifics. 

I'd eventually like to be able to write a utility that let's me see the
original path names of backed-up files (easy) and let's me restore them
(trickier, especially since one file may be split across many diskettes).

Anyone out there at Microsoft able to provide any information?  Thanks
in advance.
