I've copied out all the files from my old 32GB MicroSDHC to my computer, it's around 27GB in total. When I tried to copy them back, I noticed that some files were actually larger than 4GB thus won't be able to restore due to the FAT32 format Switch uses. (Within /Nintendo/Contents/registered) Was that some kind of protection just like those "big files" back in the old CD days or it's something else? Note: Yes I'm aware that those files were encrypted and lock to a specific SD card and console. But that's not what I'm asking here. EDIT - Never mind. Seems Finder was showing a different size than the "real" one so it won't let me. With cp command I can copy those files as they were exactly 4.0GB according to ls -lh.
