To use my 64gb SD card on my 3DS, I have to format it to exFAT. However, when it is in this format, I can't have any files in it larger than 4gb or I get an error message ("file is too large for destination file system"). Pokemon UM is 4.1gb so I need the SD card to be exFAT for it to work but I need it to be NFTS to put Pokemon UM on it. What do?
