So I moved 6 games from the nand to the USB HDD. 5 of them were installed brazilian USB, 1 was from nintendo e-shop. Before there was 2.5GB free of the 32GB. When I wanted to move them back to the nand, it says there isn't enough room. Is this because I lost some space, or is it because wupinstaller isn't as picky about free space as nintendos own tools are? Thanks. Not really a problem for me, just wondered.
