Hi I am trying to copy all the information from my original 4gb SD card to a new 32gb SD card but keep coming up against a problem with the Nintendo 3DS file. The reason I need to upgrade my SD card is I have followed the tutorials etc to add Decrypt/Homebrew/Lumia etc and need to store some games. When trying to copy the card It keeps saying that the Nintendo 3DS folder source code is too long etc (Has files with loads of letters and numbers) and it can't be copied. I have tried copying it to the desktop and this keeps happening. I take it that I need to keep the folders exactly as they are? Any help appreciated as I am banging my head against a brick wall now.
