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 : Use in-game UI options to configure game instead editing this file, unless You know what You doing.
Note: All changes via in-game UI options are saved into .cfg file on successful game exit.
- Armed Assault: The arma.cfg file is located in %userprofile%\Documents\ARMA\arma.cfg
- Armed Assault 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

Custom Name and Location
You can change the naming with the startup parameter -cfg=<string>.
The file will be then located in your game directory instead.
