What is a .CFG file extension

The CFG file extension is the format for store configuration files. The files with the .cfg are created to change program settings. You should not modify it in any way.

These files are for various computer applications, Operating Systems and processes for definition of initial settings. Any computer program can use files in the .cfg. But the location can give the user information as to what program uses it.

Usually, files with the .cfg extension are line based. Which means that it only contains one line for every setting. It does not have any strong conventions or set standards. They can also be in ASCII. You can view them using any basic text editor.

Any file that ends with CFG is a file containing configuration settings that are used on a computer. The file has a plain text format. This means it is possible to use a free plain text. Consequently, it is possible to use a plain text editor. You can also get the text editor for free.

A good example of a free text editor is the Windows Notepad that is already on your computer.

You can use the Notepad to edit, open and save the file in the CFG format. Each of the CFG files contains its personal settings for a Windows program. Also, you can store and open them without the involvement of third-party software.

Types of .CFG files

The .cfg file extension has seven different types of files. See below:

  • LightWave Configuration
  • Celestia Configuration
  • Wesnoth Markup language
  • Cal3D Model Configuration
  • Citrix Server Connection
  • MAME Configuration
  • Configuration File

Celestia Development Team developed the file. And it is a Settings File type.

It is in the Text format. The .cfg is a 3D universe simulation program. After being saved as a plain text, the file will specify the data files to be loaded when you start the program.

The end user can also edit the program. But should be carried out carefully. Any form of improper change to this file can bring about a failure in the loading process.

Cal3D Model Configuration File is an open source character animation toolkit. It is a three-dimensional model configuration file and used by Cal3D. The file is also in the Text format and contains several references to model components.

It is also  for combining all model components together. The file contains several references to Cal3D files, like .xsf and .csf extensions, as well as animation files. It also contains meshes and materials files. The .cfg can store the root directory for the model scale and referenced files.

The MAME Configuration File is a settings file and comes in the XML format. The file is in arcade video game emulators and also contains hotkeys and keyboard mapping in playing games.

It is equally used in the configuration of keyboard controls depending on the preferences of the player. You can save different .cfg files for different games.

It gives the game players the ability to easily customize game controls separately based on the game that is currently being played. The file can be accessed both on Windows and Mac operating system.

The configuration file is also another Settings File and comes in the text format. The file is called .cfg association 4 and is a generic preference file capable of storing configurations and settings information.

It is also used by many programs, which translates to the fact that various .cfg files can store data in various formats. It is not advisable to open .cfg files manually. However,you can view them using a text editor if you save it in the text format.

.cfg files based on text formatting usually contain one value and variable per line in different formats.

The program can also generate a default .cfg automatically and this can be tested by moving the configuration file away from the default directory anytime the program is not currently running.

Afterward, you can open the program to examine the directory for any newly created files. You can delete or move the files to revert to the default settings of the program.

In the case of Linux configuration, the .conf extension is better than the .cfg extension. This type can also be opened using various programs in Windows and Mac Operating Systems.

The Citrix Server Connection File is a Settings File from Citrix Systems. The file contains the required connection information needed to connect the Citrix server. It may also include a password, username, server port, IP address, hostname and so on.

Citrix client software may use multiple .cfg for connecting to various servers. You can open This file  various Linux, Mac, and Windows programs.

The Battle for Wesnoth developed the Wesnoth Markup Language File. They are game files and comes in the Text format. The file is a turn-based strategy game file for Linux, Windows, and Mac.

It is also available for free. The source code of the file is in the Wesnoth Markup Language (WML). The file is a proprietary language especially for the creation of units, campaigns, scenarios and other contents of the game, The Battle for Wesnoth.

You can use a text editor to edit CFG files. Some WML plugins that highlight syntax have also been developed for various text editors, Vi and Emacs, for example.

Newtek developed LightWave Configuration File . It is a Settings File. A preference file for rendering and modeling applications for all animation and frames sequences.

It equally used in saving different categories of application configuration options, as well as, to remember presets for the end user.

Celestial configuration files can contain references to several data files like .txf, font definition, .cel scripts, .dsc data files, .ssc and .stc.

.CFG File Extension

CFG files, also known as configuration files, are used by many computer applications, processes and operating systems to define their initial settings.

Potentially, any computer program could use a configuration file (.cfg) so it is not possible to list them all here. However, the location of the .cfg file can often provide clues as to which program created/uses it.

These files are usually line based, meaning they contain one line per setting. However, configuration files do not have any set standards or strong conventions. Recently, XML and YAML have become a popular format for config files as the format provides well-defined syntaxes and tools are available to validate and verify the syntax.

Generally, configuration files are written in ASCII and can be opened using a standard text editor, although you'll need to make sure the configuration file is not in use and that any changes are not saved when closing the file (unless you know what you are changing is safe).

How to Open CFG Config Files on Windows 10

When receiving files on your Windows 10, you may sometimes encounter new types of files that may be unfamiliar to you. Opening it with your default app may not always work. One example is the CFG File. Let’s talk first about what a CFG File is.

What is a CFG File on Windows?

CFG files are configuration or config files for computer applications and programs. It contains configuration data and settings that software developers used to write in apps and even games. Developers use the files to modify parameters in a program or an app.


Both Windows and Mac computers recognize CFG files. It typically comes in a text file with a standard format of JSON or XML. The files can easily be changed or edited. Still, you need to know where open or edit them. Otherwise, it will affect the software where you will use it.

Editing a CFG file will result in a change in the configuration in the app. So if you try to open or edit a CFG file, make sure you know what you are doing.

How to Open a CFG File on Windows 10 Computer

What is a  CFG File

The .CFG file extension is the acronym for Configuration File. It was developed by the Celestia Development Team.

The file belongs to the Settings Files category and written in the text format. This settings ✅file extension .cfg✅ is used by Celestia, which is a 3D universe simulation program. Celestia appends the extension .cf to the suffix of the filename.

The file can be saved in plain text formats and also developed to specify the data files to automatically load when the program begins to run.

The file can be easily edited by the end user but the editing should be done very carefully because any improper change to this file can lead to a failure in the loading process. The CFG file contains references to various files, like the .TXF font definitions, .CEL scripts, DSC data file, .SSC data file and even .STC data file.

The file extension CFG can be used by programmers to write various programs the file stores configuration and settings information for programs. There are different types of CFG files and they store data in different formats. The files equally contain value and variable per line.

The text editors are required for editing or reading the CFG file and this is even more so in Windows operating system. In the remaining part of this write-up, you will learn about how to open a CFG file.

How to open CFG file

If you are using windows operating system, especially Windows 10, then you can easily open the CFG file by default on your computer using a standalone file text editor and dedicated software. Some of which come preinstalled to your computer.


Instructions and steps:

  1. Find your .cfg file.
  2. Double click on it's icon.
  3. In the open with drop down select notepad or other text editor.
  4. View and edit it in your editor in Windows.


CFG file can be opened using Microsoft Notepad, which is a very popular text editor and has a global reach being used by millions of people from across the globe. Notepad may be used for basic coding by many developers, but it has a simple text editor that can be used on all windows operating system.

Notepad supports CFG file formats and also supports more than 15 text encoding formats.

Notepad is somewhat limited to the basic formatting features, but it is still possible to modify, edit and view CFG source code files on it, which makes it a powerful, but simple text editor for opening CFG files in windows.

Notepad can be used to open a CFG file by default because it is already built into Windows operating systems.

Microsoft WordPad is yet another computer program that can be used to open CFG files. The Microsoft WordPad comes as a default program on most Windows operating systems.

Just like the Microsoft Notepad mentioned earlier, Microsoft WordPad is a text editor, but it is from Microsoft Word; this makes Microsoft WordPad more of a hybrid text editor.

The features are more than what you can get on Microsoft Notepad and you can use the WordPad to embed objects like images and shapes to your text document; it can also be used to embed links. WordPad is a handy tool and does not require many graphic details.

The advanced feature it has makes it a better tool for opening the CFG file. Other tools that can be used to open the CFG files are Notepad++, NoteTab, PSPad and so on.


When you encounter a file type that you (and your operating system) doesn’t recognize, it’s often difficult to figure out how to open it. After all, every file has software that opens it, from DAT files in Windows to Office formats like DOCX or PPTX. Even files without extensions require the right software to open them. 

One file format that you might not recognize is the CFG file format, but what is a CFG file?CFG files are typically generic configuration files for other software, including applications and games, and are supported by Windows and Mac. Here’s everything you need to know about CFG files (including how to open them).

What Is a CFG File and Is It Safe?

The “CFG”in CFG file stands for configuration, which succinctly sums up its purpose for Windows and Mac users. CFG files are configuration files used by other software to customize how things work. Alternative file types, such as “CONFIG”for CONFIG files, work in a similar way.

As a universally-recognized standard, CFG files are easily recognized by Windows and Mac, but that doesn’t mean the files themselves follow a typical format. While CFG files are a form of text file and can be changed easily, you’ll need to take care when you’re opening or editing them.

For instance, changing options in a CFG file used by a piece of software may result in that software no longer working correctly. Editing game configuration files is one example, where changing the way a character operates by modifying options in the linked CFG files could make the character undefeatable (or, by contrast, easily defeated).

Typical CFG files will use a standard format, such as XML or JSON, making it easier to edit. Some CFG files, however, use a custom format and style designed by the developers. This makes it harder to change those files without relying on developer support (or by using trial-and-error).

Before you start editing a CFG file, you should understand how it will impact the software it links to. The software developers may encourage this, offering documentation or help guides to help you. Some developers actively discourage this, however, leaving trial-and-error as the only way to see if your changes work.

If you’re unsure about the changes you’re making, make sure to back up your files first. If the changes are wrong or cause instability, you can easily revert back to an earlier, backed up version of the file.

How to Open CFG Files on Windows 10

The CFG file extension is widely recognized as a software configuration file, which is why software developers often use it. The range of software using CFG files for configuration is vast, including commercial design software, text editors, and games.

That makes it easy for Windows 10 users to open a CFG file using the built-in Notepad application. However, Notepad offers no additional formatting options, making it harder to work through a large CFG file. Third-party Notepad replacements offer more features, including Notepad++, but aren’t essential.

  1. To open a CFG file using the native Notepad app, open Windows File Explorer at the location of the file. If Windows automatically recognizes the CFG file, double-click it to open it in Notepad. Alternatively, right-click the CFG file and select the Open With option.
  1. In the How do you want to open this file? menu, select the More Apps option. From the list, choose a suitable text file reader, such as Notepad, Notepad++, or Wordpad. While Microsoft Word fits into this category, Word converts CFG files into an unusual format that affects the formatting of the file, so avoid using it for CFG files.

    If you want the software you’ve selected to always open a CFG file, select the Always use this file to open .cfg files checkbox. Select the OK button to open the file.

Once the file opens in your chosen text file editor, you can make changes. But be sure to save the file in the CFG format afterwards. Some text editors, such as Wordpad, may automatically convert your file to the TXT file format during the save process.

If this happens, the file will no longer work as a configuration file, so make sure to check that the file is saved with the CFG extension once you’ve finished editing it.

How to Open CFG Files on Mac

Like Windows software, software designed for Macs use the CFG (or CONFIG) file format for additional configuration. macOS recognizes the file and should automatically attempt to open it using the built-in TextEdit app.

Like Notepad for Windows, however, TextEdit isn’t designed for formatting. If you’re dealing with a large CFG file with a lot of options, it can be easier to understand and edit it using third-party editors like Atomor MacVim. But using TextEdit is the best option if you’re looking for a built-in CFG editor for Mac.

  1. To open a CFG file on Mac using TextEdit, open the Finder app and locate the CFG file you’re looking to open. If your Mac is configured to do so, double-click the file. It should open in TextEdit automatically. If it doesn’t, right-click the file and select Open With > Other from the options menu.
  1. In the Choose an application box, find a suitable app to open the CFG file from the Applications folder (for instance, TextEdit or Atom). If you want to associate the CFG file with that software, select the Always Open With checkbox, saving you time and ensuring that all future CFG files will open automatically. It will also open the CFG file you’ve selected afterwards. When you’re ready, select Open to open the file.

Like CFG files on Windows, you’ll need to make sure that you correctly edit the file using the format it’s in (eg. following JSON styling if the file uses the JSON format). If you make incorrect changes to the file, your software could stop working.

You’ll also need to make sure that your chosen text editor saves the file in the CFG file format. TextEdit will automatically save over the existing file without changing the format. If you’re using a third-party text editor, however, you’ll need to confirm that it defaults to CFG during the file saving process.

Configuring Software on Windows and Mac

Thanks to apps like Notepad and TextEdit, you don’t need third-party apps to edit CFG files on Windows and Mac unless you’re looking for extra features. This gives you the freedom to quickly configure software and games with ease, as long as you make sure to back up your files first. 

After all, one small change can entirely break the software you’re using, especially for critical configuration files. If you’re worried, you can restore previous versions of files in both Windows 10 and Mac, or you can think about using a third-party solution like Google Backup and Sync to keep your configuration files safe instead.
