I cannot find the AppData folder mentioned in the MDK, does anyone else have this issue? Is there anything I missed?
It’s sometimes hidden.
Put just enter %appdata% in the command field and then it should get opened. Of course that is valid for Windows OS only.
Press Win + R and type %AppData%.
with a OS reinstall my mods moved to C:\Program Files (x86)\Steam\steamapps\workshop\content
Those are the mods which you are subscribed to at the Steam Workshop.
Native mods in the Appdata directory have to be saved manually.
