This sets the icon that shows up in "My Computer" when your Kindle is plugged in.

Simply copy "autorun.inf" and the icon you want to the root of the user storage.

To change what icon is shown, simply open autorun.inf and change line 2. It's set to the graphite icon by default.

You can use your own icon, too. I recommend it to be 48x48 pixels with transparency.
