Have you encountered a problem with a CFG file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a CFG file here. In the further part of this page we have added a list of programs that should open your CFG file. It is enough you choose a proper application for your operating system, download and install it.


The file extension CFG is used for configuration files, ie configuration files. CFG files are used by a large number of user programs, but also many games.

For example, while user programs store network settings or paths in them, CFG files often contain graphics and sound settings in games. Many CFG files are simple text files that can also be opened and edited with a text editor. Most CFG files contain a list of variables to which a value is assigned. Changing such a value can affect the associated program or game.

In addition to the CFG files in plain text format, there are also those in binary format or in compressed form. These can only be read and changed by the corresponding program. In general, CFG files can not be opened by the user in a program, but have to be in the default directory of the corresponding program or game and are loaded automatically.

It is usually not possible to use the contents of a CFG file to close the associated program. In addition, CFG files are not compatible with each other since each program expects different entries (e.g., variables).

Some programs have a routine for creating a standard CFG file, should none exist. Deletes or shifts (recommended) so the CFG file (the program should not be running), the next time the program is started (as such a function is available), a new CFG is created and all the settings regulated over it to the original value. You may also get an error message.

On Linux systems, configuration files have the file extension conf in the normal case instead of cfg.

Programs which can open a CFG file

How to open a CFG file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the CFG file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a CFG file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support CFG files. At this point we are looking for disk space where the application was installed in and we can link it with a CFG file. Since then, our operating system will use the selected program to support all CFG files.

Other issues

Despite the described problem with CFG there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the CFG file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the CFG file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
