I want to re-do my modding of Skyrim so as to download mods with NMM and install with BAIN, rather that doing manual downloads. However, my current modding setup seems to be pretty stable and I'm afraid of losing everything. I therefore want to copy my entire installation over to an external hard drive so that if something goes wrong with my new installation, I'll be able to just drag and drop everything to where it was before. Could someone please tell me what folders (and perhaps loose files) I need to copy to make sure everything is preserved?
