How to Change File Extension in Windows 11: A Step-by-Step Guide - i5 Apps (2024)

Changing a file extension in Windows 11 is a straightforward process that can be completed in a few simple steps. By enabling file name extensions in the File Explorer and renaming the file, you can change the extension to suit your needs. This task is useful when you need a file to be recognized by a different program or to change the way the file behaves. In the next sections, we will guide you step-by-step through this process.

How to Change File Extension in Windows 11

Changing a file extension in Windows 11 can be a handy trick when you need a file to be compatible with a different program. This section will guide you through the steps needed to accomplish this task.

Step 1: Open File Explorer

The first thing you’ll need to do is open File Explorer on your Windows 11 device.

To do this, you can click on the folder icon in your taskbar or press the Win + E keys on your keyboard. This will bring up the File Explorer window, where you can access all your files and folders.

Step 2: Enable File Name Extensions

Next, you need to enable file name extensions to see and change them.

In the File Explorer window, click on the ‘View’ tab at the top, then select ‘Show’ in the dropdown menu, and finally check the ‘File name extensions’ option. This will allow you to see the extensions of all files.

Step 3: Locate the File

Now, find the file for which you want to change the extension.

Navigate through your folders in File Explorer until you locate the file. Make sure you have the correct file, as changing the extension can affect how it operates.

Step 4: Rename the File

Right-click on the file and choose ‘Rename’ from the context menu.

You can also select the file and press F2 on your keyboard to rename it. Change the part after the dot (.) to the new extension you want. For example, change ‘.txt’ to ‘.docx’ if you want it to open with a word processor.

Step 5: Confirm the Change

After renaming, confirm the change when prompted by Windows.

Windows 11 will warn you that changing the file extension might render the file unusable. Click ‘Yes’ to proceed if you are sure about the change.

After completing these steps, your file will now have the new extension. It’s important to note that changing a file extension doesn’t convert the file type; it only changes how the file is recognized by the system.

Tips for Changing File Extension in Windows 11

• Always make a backup of your file before changing its extension, just in case something goes wrong.
• Understand the file types and extensions before changing them to avoid any compatibility issues.
• Use this method only when you know what you’re doing, as incorrect changes can corrupt your files.
• Be cautious with executable files (.exe), as changing their extensions can cause issues with your programs.
• If you need to convert a file type rather than just change its extension, use a dedicated file conversion tool.
