CFG files store settings for a specific application. They are used by several different programs and are typically saved within a subfolder of the main application directory.

Configuration files are often saved as plain text files and can be opened and edited with a text editor. However, they typically should not be modified, since altering a CFG file may make the associated program inoperable.
