What is a CFG file?

A CFG file is a generic preference file that stores settings and configuration information. It is used by various programs, which means different CFG files may store data in different formats. CFG files typically should not be opened manually but may be saved in a text format that can be viewed in a text editor.

More Information

Generic configuration files are often named "config.cfg". Text-based CFG files often contain one variable and value per line in the following format:

var1=low var2=med var3=high

To test if a program automatically generates a default CFG file, move the configuration file out of the default directory when the program is not running. Then open the program and check the directory to see if a new CFG file has been created. Also, a CFG file can sometimes be moved or deleted to revert to a program's default settings.

NOTE: Linux configuration files typically use the .CONF extension rather than CFG.

Source Engine Configuration File

Developer	Valve
Popularity	4.3 | 3 Votes

A CFG file may also be a configuration file used by a Valve Source Engine video game, such as Half-Life 2. It contains a newline-delimited list of plain text commands that modify a game's settings. Players can execute the commands a CFG file contains manually, via a game's Developer Console, or automatically, by placing them in an appropriate game directory.

More Information

Source is a 3D game engine that Valve used to develop Half-Life 2, Garry's Mod, Team Fortress 2, Portal, and many other games. Games developed using the Source engine use a variety of CFG configuration files to load data and set certain game settings.

While most players will never need to open or edit a CFG file, game modders sometimes create and use their own, custom CFG files. They then execute the commands these files contain by either:

• Loading them via a game's Developer Console
• Placing them in an appropriate game directory, from which they are loaded automatically

For example, a modder may place a modsettings.cfg file in a game's mod directory and use it to load a game mod. Or, a modder may replace a game's autoexec.cfg file with a customized version of that file, used to modify the game's gameplay (for example, by enabling cheats).

Common CFG Filenames

autoexec.cfg - Contains commands run at game startup.

modsettings.cfg - Contains commands used to load and apply game mods.

How to open a CFG file

You can open a CFG file and edit the commands it contains with Microsoft Visual Studio Code or any other text editor.

M.U.G.E.N Configuration File

Developer	Elecbyte
Popularity	4.0 | 3 Votes

A CFG file may also be a configuration file used by M.U.G.E.N, a free sprite-based game engine used to create 2D fighting games. It contains settings that control a fighting game's gameplay, sounds, and appearance. CFG files used with M.U.G.E.N are typically named mugen.cfg.

More Information

A M.U.G.E.N CFG file allows fighting game creators to modify their game's basic rules, including round time, game difficulty, game speed, combo damage multipliers, and more. It also allows creators to choose what resolution M.U.G.E.N shows their game at, as well as whether M.U.G.E.N should play sound effects and music. Advanced M.U.G.E.N users can customize a number of additional game-related settings using a CFG file.

M.U.G.E.N's default CFG file, mugen.cfg, is stored in the program's data folder. While you can edit game settings directly within mugen.cfg, it's recommended that you create a copy of the file before editing it, so you can easily revert M.U.G.E.N to its original settings if necessary.

Common CFG Filenames

mugen.cfg - The default configuration file included with M.U.G.E.N. It is located in the program's data folder.

How to open a CFG file

Because they are plain text documents, you can open mugen.cfg or any other M.U.G.E.N CFG file with any text editor. In Windows, you can open a CFG file with Microsoft Notepad or Microsoft WordPad. In macOS, you can use Apple TextEdit.
