What is a VCFG file?

A VCFG file is a configuration file used by the Valve Source 2 game engine. It contains one or more console commands that modify a Source 2 game. Source 2 games contain default VCFG files, which modders can modify to alter how the games function.

More Information

Source 2 is a proprietary game engine Valve has used to create games such as Dota 2 Reborn and Half-Life: Alyx. Games created with Source 2 include VCFG scripts, which typically configure certain game settings at startup.

While most players will never need to access or modify a game's VCFG files, modders enjoy using them to customize Source 2 games. For example, a Dota 2 Reborn player might create a script that allows them to quickly toggle their camera between runes, and then add a directive to execute that script in Dota 2 Reborn's game_convars.vcfg file. Or, a player may create an entirely new VCFG script and execute that script using Dota 2's Console.

NOTE: Source 1 engine games and some Source 2 engine games also use configuration files saved with the .cfg extension.

How to open a VCFG file

You can open and edit a VCFG file with Microsoft Visual Studio Code (multiplatform) or any other text editor. To execute the script a VCFG file contains in a Source 2 game, use the Console available in-game.
