Don't know why the downvote(s)...
I clearly remember a "compression" tool kicking about, back in the day, that would simply hide the file on your hard disc and leave a pointer to it. Totally bloody useless, and I knew a few folk (definitely older than 10, and computer-literate enough to know better) who believed they'd just packed loads of DooM WADs onto a floppy.
Wasn't part of Windows (it was a 3rd-party practical joke), but it was out there.
Edit: I also remember reports of people "compressing" all their files to floppy and then finding a hidden folder full of "crap" on their C: drive, deleting it, and losing the lot...
