CFG File Extension

Have a problem opening a .CFG file? We collect information about file formats and can explain what CFG files are. Additionally we recommend software suitable for opening or converting such files.

What is the .CFG file type?

Stemming from the MS-DOS era, the .cfg extension stands for 'Configuration' and is conventionally used in the Microsoft (MS) Windows world to denote the generic Configuration File (CFG) file type.

A configuration file is a standalone plaintext or binary file that stores a set of variables with their respective values. CFG files serve to provide initial settings to set up a user environment, adjust behavior of an operating system or configure an application.

A .cfg file is a configuration file, and most CFG files are plaintext (often XML-based), containing structured and indented text lines for easier reading and editing. Such CFG files would usually have extensive comments to explain available configuration options and syntax.

Some .cfg files in MS Windows come as binary formats and cannot be viewed/edited directly.

CFG configuration files are used by a number of different applications (incl. games) and OS components. CFG files are usually placed either in application directories or application data directories within user profiles.

In Unix-based OS'es, configuration files are traditionally labeled with the .conf or .rc extensions.
