What is an XTX file? An XTX file is a configuration file used by Xbox 360 games with the Source Engine to store settings that are normally kept in a gameinfo.txt file on other platforms. It contains the gameinfo configuration used during startup, including search paths, game metadata , dependent mods, and other settings that the engine reads when initializing the filesystem and preparing the game environment.

More Information On Xbox 360, Technical Certification Requirements prohibit plain .TXT files on game discs, so the Source Engine uses the XTX format instead. The contents of an XTX file are unencrypted and identical to the corresponding TXT version, but the format exists to meet platform requirements. The Source Engine can also fall back to the TXT version if the XTX file is not present.

How to open an XTX file

You can open XTX files with any text editor, such as Microsoft Notepad or Apple TextEdit . The XTX file is usually located in the game's root or configuration directory and is processed automatically by the Source Engine. Game modders and developers working on Source Engine projects for Xbox 360 may view or edit XTX files to adjust game settings, but they must preserve the correct text structure so the engine can read them.
