I have a folder of MP3s, some of which date back to 1999, just a few years after the format was popularised. Most of them have utterly terrible names (think RIDEONAM.MP3). I think at this point they might even survive the heat death of the universe. And they’ll still be terribly-organised.
Not unless you keep up with migrating your files. Drives fail over time.
Gotta have a good backup strategy for sure. I would’ve lost my collection a few times if I didn’t have one.
