I had heaps of porn once, the best way for me was to delete a lot of it. But ultimately I sorted by categories.
So for example I would have a JAV folder. Inside JAV I would have the basic sorting. So inside that folder would be Straight, Lesbian, Solo, LesbianStraight (I made that category up for a scene where women do lesbian stuff but also have sex with a guy also).
Then inside those folders I would have them sorted again by theme. So inside the straight, lesbian etc folders there would be more folders like bondage, anal, softcore etc.
I found that it was sufficient. I find that if you have so much porn that you can't figure out anyway to sort it properly then maybe you have too much porn. Look at some things and think about if you are ever even going to use it to get off over, if you think you probably won't then just delete it I would say. Just keep the really good stuff.
I did this with my collection to consolodate it, I made a folder called best and went through all of my porn and only put the very best things in it to keep. I once had like literally 3TB of porn. But today it's down to 400gb and I will never make it larger than that.
