At what point do you delete your RAW files? Or do you keep everything?

I’m starting to accumulate A LOT of RAW files, and it’s becoming a bit overwhelming in terms of storage and organization.

I’m curious how others handle this long-term: Do you keep all your RAW files, even after editing? Or do you only keep the selects / edited ones and delete the rest?
Have you ever needed a RAW file years later and been glad you kept it?

Also, going through everything to sort and delete takes so much time that I sometimes just… don’t do it.

Curious what your actual workflow looks like and if you’ve found a balance between keeping flexibility and not drowning in files.
