When was the last time you used a floppy disk? I actually used one via a USB drive to transfer a file to a disconnected system at work and we have old oscilloscopes with floppy drives in them. I don't have a computer with a floppy drive at home, but there may be a few discs around.
Linux founder Linus Torvalds is declaring the floppy hardware driver orphaned. So that could be a nail in the coffin.
A lot of my early computing used audio cassettes as disk drives were expensive. I used 5.25" floppies on various computers at school and work. They came in different flavours with storage from 160kB up to 1.2MB. Later I had a couple of Amiga computers with 880kB 3.5" drive built in. I invested in a high density external drive that could store 1.6MB! Useful for backups of my 200MB hard drive.
Those were the days when software could come on multiple floppies. At one job I was sometimes installing Microsoft Office from big stack of them. You had to hope it did not fail.
I used software that split big files across multiple disks to transfer them between computers. Downloading was slow and expensive, so we would order disks of free and shareware software by mail.
Some early Sony digital cameras used 3.5" floppies for storage. You could not fit a single image from a modem camera on those.
These days I have large USB flash drives and even those are rarely used as we can transfer big files online for zero cost. Times change.
