So. Suddenly today something broke. I did not do any additional tweaks. I can still move/rename folders via CMD prompt. Renaming/reading/editing files from explorer still works just fine. But if i try to rename or move FOLDER I get error message: "Can't find specified file. The file or folder does not exist" I have tried taking ownership of folders and giving permissions. But nothing seems to work. So anyone have any idea what could be causing this and how to fix this? EDIT: I did all my registry tweaks again, including removing libs/onedrive/etc. And it's working properly again. I must have made copy & paste error somewhere. No idea what part actually fixed it or what can break explorer like that, but I'm happy it's working again.
