F.E.A.R. 2: Project Origin was developed by Monolith Productions and released in 2009. The game uses archcfg files to store configuration data.
The format is specific to the game and is not intended as a general-purpose configuration or data-exchange format.
Open an archcfg file by starting F.E.A.R. 2: Project Origin on Microsoft Windows. The game reads files of this type as part of its configuration data and does not normally require them to be opened separately.
There is no need to open the file with a general-purpose application. Editing or renaming it may prevent the game from reading its configuration correctly.
An archcfg file cannot be meaningfully converted to a standard configuration format. It should remain in the format expected by F.E.A.R. 2: Project Origin.
If configuration data must be transferred, the practical option is to use the game's own settings or copy the relevant game data rather than convert the file.
