So I've recently been trying out new texture packs to see if I like any of them and have tried Skyrim HD 2k Textures but wanted to disable the mod for a bit. I use NMM and when i disabled the mod it kept the textures that came with the mod, I tried just fully deleting the mod out of my game and NMM and they are still there. My question is how do I fully uninstalling these texutres without screwing up some of my other texture mods?.
