I threw out several hundred 3½ inch floppies when we moved house. They were full of "irreplaceable" stuff that I hadn't actually used in years. I kept about a dozen "just in case" with stuff like various levels of DOS boot, and a Linux master boot floppy that "unlocks" the old PC by running Fedora 5 on a spare partition.
I bet I never use those either!
I also chucked several boxes of 5¼ floppies with prehistoric stuff on them. I found my old 5¼ drive and connected it up last year, but Windows 7 didn't seem to like it.
The motherboard in this PC says it needs a floppy to install new BIOS, but I've not tried doing that and I doubt I will.
The floppy is heading for extinction, I fear.
