What is an ARG file?
Settings file used by AutoCAD, a 2D and 3D CAD drafting application; contains backed up user profile information (application options data) that was stored in the system registry; can be exported and imported to transfer settings between computers; can also be migrated between versions of AutoCAD.
NOTE: The LT version of AutoCAD does not use ARG files. Only the full version can export and import them.
