Ye if you moved files around and such you don’t know what you broke. This wiping your C Drive with a fresh install will fix your issues. If you’re savvy enough you can go through every single program/program 86/document folder and locate it but I’m guessing you’re not that savvy. So just reinstall windows. Put your mobo network drivers, ffxiv character settings, and if shaders for ffxiv put those on it too.
