Changing File Extension in Windows 11
Let’s dive into the step-by-step process to change a file extension in Windows 11. This guide will walk you through making this simple yet essential task.
Step 1: Open File Explorer
First, open the File Explorer by clicking on the folder icon in the taskbar.
File Explorer is your gateway to all the files on your computer. It’s like a digital file cabinet where you can find what you need.
Step 2: Navigate to the File
Locate the file whose extension you want to change.
Finding the file is crucial. Make sure you know its current location to save time. Use the search bar in File Explorer if needed.
Step 3: Enable File Name Extensions
Click “View” in the top menu, then click “Show” and ensure “File name extensions” is checked.
This step is vital because, by default, Windows doesn’t show file extensions. Enabling this feature lets you see and edit them.
Step 4: Rename the File
Right-click the file and select “Rename.” Change the extension to your desired one.
Renaming is straightforward. Just be cautious when typing the new extension; a small typo could lead to file issues.
Step 5: Confirm the Change
Press Enter and confirm the change when prompted.
A confirmation dialog will appear, warning you about potential file issues. If sure, click “Yes” to proceed.
After completing these steps, the file will now have the new extension. This change alters how the system recognizes and opens the file. Make sure the new extension matches the file type you’re aiming to convert.
