DATA.TWT is a file present in Carmageddon II's main directory. This file contains part of the game's data, which means that deleting it or renaming it will cause the game to stop functioning. Although, as with many other TWT data files, if the file isn't present, the game will try to load its contents from a folder that uses the same name. Curiously, this file has the same name as an existing folder. Carmageddon also has these files, but they're encrypted. In order to decrypt them, the player must write the IWANTTOFIDDLE cheat.
