RFA files are commonly used to modify game content. For example, several map editors can modify game maps in RFA files, which include terrain, obstacles, weapons, spawn points, and other map objects. RFA game modification files are typically stored within the following game directory:\Battlefield 1942\Mods\bf1942\Archives\. RFA stands for Refractor File Archive. The format was used by the Refractor game engine which was designed by Refraction Games. Digital Illusions CE later bought Refraction Games and the engine was used in the Battlefield 1942 game. Digital Illusions CE has been a subsidiary of Electronic Arts since 2004.
