What is a TFC file?
A TFC file is a texture file cache used by video games developed using Unreal Engine 3. Games use the textures that TFC files contain to skin 3D models. Examples of games that use TFC files include Batman: Arkham City, Rocket League, and Mass Effect 2 and 3.
The Unreal Engine is a video game development engine published by Epic Games. Epic and other developers use Unreal Engine to create 3D video games.
Games created using version 3 of the Unreal Engine often store textures in TFC files. While these games are running, they reference and apply the textures that their TFC files contain to characters, vehicles, items, and other 3D objects. For example, Rocket League contains TFC files used to skin players' vehicles.
How to open a TFC file
TFC files are not meant to be opened. Developers using Unreal Engine 3 can check their TFC files for errors using the program's verifytfc utility.
