If you've played around with your SD card as much as I have, you've undoubtably run into an issue sorting the Folders.
Even though the Atarimax gives you the option to sort the files, the inherent nature of the (F)ile (A)llocation (T)able system doesn't sort the Folders themselves (usually First in, First out).
Fear not, there is a simple solution; I've been using this on my Flash drives for years.
All you need is a "FAT Sorter" =>

Sounds silly, but works great.
You have the choice to sort one folder, or every folder.
