I am light years away from ya'll. But right now I have started arranging them in different folders by their type. Separate folders for RAW files, Non-RAW files (mainly for jpg photos), Post processing (work in progress, psd files), Finished files (all pp'd and final versions), HDRIs..
I try to keep them organized immediately. I find time to get them on the computer and organize them immediately. Or else am in a rut like Seltzer.. my lazy self is too empowering
