This article explains what a FORGE file is and how to open or convert it on your computer.

A file with the FORGE file extension is a game data file used in Ubisoft games such as Assassin's Creed. It is a container format that can contain sounds, 3D models, textures, and other things used by the game.

FORGE files are produced by Ubisoft video games such as Assassin's Creed and Prince of Persia. They are not intended to be opened manually by you, but to be used by the game itself.

However, there is a small, portable tool for Windows called Maki that should work. It should be able to extract some or all of the various components that make up the file (textures, sounds, etc.). You will need a program like 7-Zip to open the RAR archive that Maki is stored in.
