It was quite different before the internet. I'm still holding out hope of finding some of my old BASIC programs from the 80s on a 5¼-inch floppy disk in my parents' basement. But they are probably gone.
The programs weren't fancy: one was for picking lotto numbers for my mam (the national lottery had recently launched in Ireland so it was a novelty.) Also I was 10.
Even before GitHub, probably. Dropbox was a big step forward, still.
