I used the Backup program from win95 to backup many files
on floppy diskkettes long time ago. Some of these
diskettes might be lost, they may not be in order as they
were backed up originally. can I restore them even some
diskettes are missing. Can I use windows XP,
also Dos or anything else to restore them? your help is
greatly appriciated.

If you have the original backup program, this might work
on your new system. If the files are compressed and
spanned over many disks you will be out of luck im afraid !
