Introduction

The arma.cfg or arma2.cfg or arma2oa.cfg or takeonh.cfg are configuration files containing detailed information about YOUR game setup.

Information such as language, LOD detail, resolution are stored in these files.

The config files are written after the game was run for first time and the system settings are detected.

The files itself are just as editable in a text file. The content format is

variable = value;

Warning : Unless you know what you're doing, use the in-game UI options to configure the game instead of editing this file.

Note: All changes made via the in-game UI options are saved to the .cfg file on a successful game exit.

Location

Armed Assault: The arma.cfg file is located in %userprofile%\Documents\ARMA\arma.cfg

Arma 2: The arma2.cfg file is located in %userprofile%\Documents\ARMA 2\arma2.cfg

Operation Arrowhead: The arma2oa.cfg file is located in %userprofile%\Documents\ArmA 2 Expansion\arma2oa.cfg

Take On Helicopters: The takeonh.cfg file is located in %userprofile%\Documents\Take On Helicopters\takeonh.cfg

Custom Name and Location

You can change the naming with the startup parameter -cfg=<string>.

-cfg=myGameSettings.cfg

The file will be then located in your game directory instead.

c:\arma2\myGameSettings.cfg
