Hi again Ray
That 1980's programme might have been PCTools.
I bought my first computer (a wonderful commodore 64) around March 1984 and had a tape drive originally.
Later on, we used to use PCTools on the old 5.25 inch disks to try to fix file damage or to edit high scores and stuff like that.
Used to be fun but the downside was that 10% of the time one would have success and 90% of the time, would muck things up even worse than what they were
Floppies like that used to be so unreliable compared to today's data storage but then again, back then we thought a 5.25 inch 360 kb (I think) was pretty awesome. 3.5inch disks emerged around then also and if you drilled a hole in the opposite side and were lucky you could use both sides of a single sided 3.5 and double the capacity.
Ahh, those were the days my friend!
Good luck with your exe search
Cheers
Graham
