Depends on where you're saving it. Personally, I use reddits save function till I can be bothered to transfer everything to Discord (I have my own server, with specific channels and such) maybe instead of deleting it, you could do something like that?

Never really saved to pc or such before since I haven't really had one of my own. You could also try Google Drive and such. You could always open accounts and such. Like I have Pornhub, Hanime, Nhentai etc.

If you mean just straight up deleting porn, personally I'd look at what I've rarely gone back to. There's some porn I go to every week or two and stuff I've looked at once.

Dunno if there's are what you wanted, but that's how I read it. If I'm wrong, feel free to clarify. I'll try better.
