How do I organize my Mods folder when it comes to gameplay mods?

@logion So basically all my animations the .package files I can literally just put them in one folder and they'll be okay with other mods that use this specific animation? Have you heard of things called A modder file when downloading a mod? It said right next to it not a mod so maybe it was just instructions that I didn't need to necessarily put in my game? Also two more questions if that's okay I noticed a Json file and a xml file in my mods folder when downloading a bunch of stuff is it safe to delete these?
