Consequently when you run for example the exe from directory 2, you can setup a unique UI for that particular instance.
I would probably not do it this way. Symlink will use much less space and accomplish the same end goals. I would copy only over the WTF folder, and the exe and symlink nearly everything else. The only problem with Symlinking is when the game is patched that can cause a few issues for sure
