Changing a file extension in Windows 11 is a straightforward process that can be tackled in just a few steps. You’ll start by adjusting your File Explorer settings to reveal file extensions, then simply rename the file to include the new extension. This quick guide will walk you through each step, ensuring you can change file extensions with ease.
Changing File Extension in Windows 11
Changing a file extension can alter how your computer reads the file, so it’s essential to follow these steps carefully to ensure the file works correctly after the change.
Step 1: Open File Explorer
Open File Explorer by clicking the folder icon in the taskbar or pressing the Windows + E keys.
Once you’ve opened File Explorer, you’ll have access to all your files and folders, which you can navigate to find the file you want to change.
Step 2: Enable File Name Extensions
Click the "View" tab at the top of File Explorer, then check the box for "File name extensions."
This step shows the file extensions (like .txt, .jpg) next to file names, making it possible to change them. If you skip this, you won’t be able to see what needs to be changed.
Step 3: Locate the File
Navigate to the folder where your file is stored.
If you know the file’s location, head straight there. Otherwise, use the search bar in File Explorer to find it quickly.
Step 4: Rename the File
Right-click the file and select "Rename," or just click the file name. Change the extension after the dot, such as from .txt to .doc.
When renaming, ensure you only change the extension, not the file name itself, to avoid confusion later.
Step 5: Confirm the Change
Press Enter, and when prompted, confirm that you want to change the extension.
A warning might appear, reminding you that changing file extensions could make the file unusable. If you are sure, go ahead and confirm.
After completing these steps, your file will now function as the new extension type. You can test it by opening the file to ensure it’s working correctly.

- Not all files can be safely changed; some might become unusable.
- Use a dedicated file conversion tool for complex file types if needed.
