Actually, I take this back. I just looked at the documentation, and the list of different save sizes is 2KB, 8KB, 32KB, and 128KB (128KB won't be supported for obvious reasons). I guess a 2KB save would, obviously, be in a 2KB appvar... but the 8KB and 32KB are what should be affected by this poll.

But if there are multiple parts, one part of the save can accidentally get deleted and you game is messed up.
