The .zip file contains 3 blank versions of the icon images used for the basic models that come with the game. The point of downloading this small file is to give a skin/model a more professional looking edge over other models so it fits in with the standard models easily without looking out of place. There isn't much else to say, if you're looking for a way to make your WIP skin/model look a bit more fitting then this file is for you.
