Opening CFG files

Did your computer fail to open a CFG file? We explain what CFG files are and recommend software that we know can open or convert your CFG files.

What is a CFG file?

The .cfg file extension is assigned to a computer's configuration files. Configuration files are used by a wide range of programs and applications. The information within some CFG files contains a program's initial configuration and settings.

Some files with the .cfg file extension are also created when you change the settings of a particular program or computer application. For example, if you change the interface settings of a particular application the application will create a new CFG file to accommodate those settings.

Files that have the .cfg file extension are usually written in ASCII code, although the files may be stored in a different format depending on the application that it was created with.
