You can copy >4gb files onto your Switch by FTP or MTP. The Switch OS uses a trick to store them in multiple files but treat them as one automatically.The ISO's and RVZ are over 4GB. Switch's FAT32 filesystem does not support files larger than 4GB. I don't want to scrub Subspace Emissary. So I have to split the game.
EDIT: I guess Dolphin doesn't support split WBFS files. Sigh.
