Hmm... Lessee...

C:\Long Directory Name> dir

  Volume in drive C has no label
  Volume Serial Number is DEAD-BEEF
  Directory of C:\Long Directory Name

THISIS~1 NAM   <DIR>        04-22-99 10:03a This Is A Long.Name
THISIS~2 NAM   <DIR>        04-04-00  6:37p This Is A Longer.Name
THISIS~3 NAM   <DIR>        04-22-99 12:24p This Is A Long.Name~
          0 file(s)              0 bytes
          3 dir(s)     254,705,664 bytes free

So... How do you restore the backup of THISIS~1.NAM? (For the sake of 
argument, it was created using Vim for Win32. ;) Can you differentiate 
between the three of these somehow? I'm not trying to be difficult. I'm 
just curious. I would love to find a way to do this from "real" DOS.

P.S. (as I'm about to queue the message...) Is there a way to format disks 
to have a specific serial number? And can it be compiled into a DJGPP 
program? (That oughta keep this in the scope of the group... ;)
