Thanks but as I said, it's about the collecting, not the watching. I captured/filtered/converted shows like Buzz Lightyear of Star Command for my nephew 25 years ago. I'm not going to delete it despite that no one is watching it or will watch it for decades (maybe when nephew has kids or if I have grandkids). It's not even available on any streaming.

I think if I ran maintainerr, it would tell me to delete everything except the home videos that my mother in law likes to watch.
