In the following steps, you’ll learn how to change a TXT file to a CFG file using basic features available in Windows 11. This simple task will involve renaming the file extension, which is a small yet crucial part of customizing your software settings.

Step 1: Open File Explorer

First, open File Explorer by clicking the folder icon in your taskbar or pressing Win + E on your keyboard.

The File Explorer is your gateway to all the files and folders on your computer. It’s where you’ll navigate to locate the TXT file you want to change.

Step 2: Locate the TXT File

Find the file you want to convert. Maybe it’s on your Desktop or tucked away in a folder. Either way, make sure you know where it is.

Step 3: Enable File Extensions

Windows will ask if you’re sure about changing the file extension. Click "Yes" to proceed.

Once you complete these steps, your TXT file will be renamed to a CFG file. This change allows the file to be used as a configuration file by various software programs.

Tips for Changing a TXT File to CFG in Windows 11

  • Backup Your File: Always create a copy of your original TXT file before changing the extension.

  • Use Safe Names: Avoid using special characters in the file name.
  • Know the Software Requirements: Ensure the software needing the CFG file accepts the newly renamed file.
