What is a CONFIG file?

Files that contain the .config file extension are used by the Microsoft NET framework and are created during application development. The CONFIG files are used by a variety of NET framework applications. These files contain the configuration information about the program that they correspond to, including the settings and preferences of the specific application.

The CONFIG files are developer files, storing information about the associated application. These files are normally stored in a text-based format. The file name will normally reference the associated application. For example, a filename.exe executable program would usually have a filename.config configuration file associated with it.
