I do sample them every few years out of curiosity. They mostly contain very old software and game kits from the late 90s and early 2000s so the data is only interesting for historical reasons. I also check them visually for disc rot but so far there hasn’t been any. Which makes sense because they’re not scratched, and they’re stored inside CD wallets put inside boxes put inside a dry cupboard at room temperature so environmental contamination is not likely.
