Restore from DOS 5.0 backup

It never ceases to amaze me what some customers require from us. Recently a customer called wanting to restore files from an old backup they had. As it turns out this backup was stored on a floppy disk in a safety deposit box for who knows how long.

The customer was able to get he files off the floppy before I even took a look. The backup consisted of 2 files, BACKUP.001 and CONTROL.001. It turns out this is a backup from DOS 5.0, this requires the use of to restore the files.

Then it is simply a matter of running

c:\ a: c:\*.* /s

Of course then I had the fun task of converting everything from Works 4.0 to a doc. I managed to do this using a virtual machine, and Microsoft Works 95. Trying to use Office and the works converter didn’t work, it either failed with a nondescript error message or just displayed garbage.
