Oh memories of stacking those, and going to my friend's place to copy the latest games :) Remember how we were drilling holes to doubled the disk's storage capacity (from 720 to 1440) https://www.vogons.org/viewtopic.php?t=47247
Before the floppy disks we were using cassettes... with our TO7 (circa 1983). It was slow by our current measure, but as kids we had time, I guess. The TO7 had even a lightpen to point at the CRC screen. https://en.wikipedia.org/wiki/Thomson_TO7
My parents attic has still some of my old floppy disks, and even maybe some cassettes.
