Its pretty much the title I'm just genuinely wondering how you guys are keeping track of all of your legally sourced files. I'm pretty much just relying on a spreadsheet but is that really the best way? Especially for the less technically inclined individuals such as myself

Edit: I apologize thought it was obvious but looking back I could've been more specific. I was referring to movies, TV shows, YouTube videos, books, audiobooks, etc. I haven't taken the leap to self host anything yet just growing my library for now on a couple of encrypted drives until the time comes. You don't really need to provide tailored answers towards my situation I just want to know what's out there in terms of keeping track of stuff. Thank you in advance since this account is a burner and I check it like once a day

Edit #2: appreciate all of your feedback. Seems the majority rely on jellyfin and other software to automatically check what you have stored which I didn't even know it could do that's interesting.
