I have a collection of files from the late ´90s and early ´00s. Many of them are .JPG, .MP3, .WAV, instead of .jpg, .mp3, and .wav. Why was that the norm at the time? I usually just change the extension myself.

To keep their competitors from buying them and scanning them.









Sorry, but I did an oopsie. I watched the video linked, they destroy the books to scan them. It’s really sad. Though I’m sure they would destroy them anyway.
