Like 3 months ago, cleaning out some boxes from the basement. If that counts as using them? I loaded them up, copied some files. Wrote files to a few, lol.
Nothing great on any of them. A couple form templates from my dad or uncle's work, some drivers for hardware my uncle used to have. Maybe a couple clipart collections? Or those might have been on CD.
I put a bunch of blank ones out at the yard sale we had, people ended up buying them. /shrug
Before that, if I ignore other similar cleanout/backup situations, I think I used some floppies for school assignments in middle grades.
I think also maybe at some point in between I had tried to use a boot floppy on an old computer to rescue files or install Linux.
