[comp.sys.ibm.pc] Backup file formats...

mamos@uafhp.uark.edu (Mark _E_ Amos) (04/21/91)

  I have a file with a .TD0 extension that appears to be a backup format
  of some kind when I examine it.  I resort to posting because the data 
  within is very important to us, and I have exhausted all other means at
  my disposal.  Does anyone know if this is disk backup file extension and,
  if so, what program is necessary to "extract" it?

  Thanks

Digging back into the dank recesses of my mind, I seem to recall this
is a file created by TELEDISK, a program that makes a file copy of a
disk (neat for taking a system disk and sending it via email, etc.).
TELEDISK allows compression of the file to save space, as well as
some other nice features (like providing EXACT copies of a disk that
has had altered sectors imposed as a copy-protection scheme).  Works
with MS-DOS only, as far as I can tell.

There's a copy of this on simtel under the name TELED212.ZIP in the
DSKUTL directory.  If you don't have access to ftp, let me know and
I'll uuencode it and send it your way.
