Hi fellow tempers!
Just wanted to know what the biggest size microSD card I can use on my 3.0.0 switch without being asked to update.
If you didn't already "update" to download the FAT64/exFAT driver, then you will need to do so...
All 64+ GB cards must be exFAT out of the box (that's the only filesystem allowed by the SDXC standard), it will probably accept SDXCs reformatted to FAT32
