copy the contents of your sd card to your comp and reformat to fat32 and no you don't have to reinstall
Oh really ? Yes I'm using Tinfoil USBIf you're saying remove the previous update, theres no need. The previous update gets overwritten. (Assuming you're using network/usb transfer.)
HOS (Switch’s OS) automatically splits all games into 4gb parts (on both exfat and fat32)But I don't need to split file or smth ? I heard that you can't copy more than 4gb ?
