Awhile back I used WUPInstaller and it ended up giving an error, I didn't think much of it at the time, but now that I check Data Management to see that only 13GB of the 32GB is being used and yet it shows only 200~ MBs free. 1. Any way to fix this currently? 2. Would I need to format the Wii U? 3. If I did format the Wii U, what will I lose/have to redo?
