So after going through a successful A9LH install and a system transfer from my Old 3ds, there seems to be a lot of extra folders in the Nintendo 3DS folder on my SD card. I seem to have 5 ID0 folders and I am wondering if it's possible to clean them up. I believe the extra ones are from the Emunand + various formatting, so now that I no longer have an emunand and everything is done are the extra ones still used/needed? One folder seems to be increasing in size as I install games, so I am assuming that is the one that is being used, with the rest being old remnants. Is it ok to delete the others?
