Alright to make it simple, I ran into so issues with my Skyrim install after using SKSE and trying (Ultimate Follower Overhaul) and afterwards (Extensive Follower Framework.) After everything was said and done while I was trying to fix everything, I was left with a very buggy game and was forced to reinstall from scratch and all the mods along with it. Now I am almost 100% certain I have downloaded and installed every single Mod I had (and a few extra!) yet I find myself having two or three folders left over in my back up folder (I copied the Skyrim directory to a folder on the desktop to use as a checklist of sorts as I reinstalled everything. Anyway, Here are the two folders below in some sense. I'm hoping one of you can tell me where they come from or what Mod adds them, to be sure I haven't missed anything. For future reference "Modfiles" is the name of the folder I was using as the checklist. Again, it is just a copy of my entire Skyrim directory. The bolded will be the folders and files in question. There is always the possibility that these are folders or files I overlooked when uninstalling mods once before, but I'll deal if it if that's the case. I just needed to be reminded of what they belong to. Mods, or Vanilla. C:\Users\Jag Blade\Desktop\Modfiles\Data\shadersfx\Lighting\059 P800C05.fxp V800400.fxp V800405.fxp VC00401.fxp C:\Users\Jag Blade\Desktop\Modfiles\Data\DialogueViews There are way too many files to list here. 1,593 in total. C:\Users\Jag Blade\Desktop\Modfiles\Data\LSData DtCdal.dat DtC6dl.dat Wt8S9bs.dat Wt8S9fs.dat Wt16M9bs.dat Wt16M9fs.dat Now as far as I know, apart from a ton of extra scripts (Yet no other ESP or BSA files to replace) that is the only thing stumping me. I have no idea what these three directories are for as none of the mods I've reinstalled have added them. Any help would be greatly appreciated, and thank you in advance!
