How do you organize your screenshots?

I haven't organized them at all. I wanted to make folders for different saves and I started it few months ago but I haven't had the time to continue and it's a huge mess. To be honest, I'd rather play the game when I have free time.
I have way too much screenshots of Sims on my laptop and recently I've been thinking of just deleting all of them. I never look at them anyway, so why keep them. Maybe I'll only keep some of my favorites.
