I tried to use this so I can dump my Zelda Breath of the Wild savefiles and... it got my USB corrupted, now I can't delete the corrupted files.
I had my game on the USB hard drive, I dumped the savefiles from there and then I deleted the old ones using the Wii U's Apps manager, when I try to restore the data using this app then it restores some savefiles without date or time and when I try to delete them the console refuses to do it, can someone help me here?.
EDIT: It doesn't matter anymore, I managed to delete the corrupted savefile thanks to Ftpiiu, however I lost my savegame, I have one in my SD Card but it seems corrupted.
