LOL I used to pop the little plastic button hinges off the back and open the filer from the back. ;)
P.S. - I just noticed that all the floppy disks in this case are upside down. I know at the end of the floppy disk era people would just write on the disk face in sharpie, but for many years I actually used the labels, and would place the disks upright so I could read them.
I did notice that - placing disks in a holder up-side down used to irk me (all right, so it still does. :P )
I don't remember ever writing on a disk directly, I tried to always use labels. For a while, I had an impact printer and a strip of mailing labels (5160-sized - https://www.avery.com/products/labels/5160) that I used for disk labels. I have even used labels from one of those old plastic DYMO embossing label maker (https://www.dymo.com/label-makers-printers/embossing-label-makers/dymo-organizer-xpress-embossing-label-maker/SAP_12965.html (https://www.dymo.com/label-makers-printers/embossing-label-makers/dymo-organizer-xpress-embossing-label-maker/SAP_12965.html). :o 8)
