many programs that I've acquired over the years that ran on pre-Win 98 operating systems: I've tested some on my work laptop running XP Pro and they won't work properly or at all. I'm not going to give up years of data that's locked inside freeware/shareware program files that never followed Microsoft's "upgrade path" or were purchased from companies that are no longer in existence.
And I still want to salvage the data files from the drive if that's possible.
