Changing the extension of a file in Windows 10 is a simple yet powerful way to control how your computer handles that file.

How to Change the Extension of a File in Windows 10
In this section, you’ll learn how to change the extension of a file in Windows 10. Each step is designed to be straightforward and easy to follow, ensuring you can complete the task without a hitch.
Step 1: Open File Explorer
First, open File Explorer by clicking on the folder icon in the taskbar or pressing Windows key + E.
File Explorer is your gateway to navigating through all the files and folders on your computer. You need to have it open to find the file whose extension you want to change.
Step 2: Go to the View Tab
In File Explorer, click on the "View" tab at the top of the window.
The "View" tab holds a variety of options for customizing how you see your files. This is where you’ll find the settings to display file extensions.
Step 3: Check the "File name extensions" Box
In the "View" tab, find and check the box labeled "File name extensions."
By checking this box, you make sure that all file extensions are visible. This is crucial because you can’t change the extension if you can’t see it!
Step 4: Navigate to the File
Go to the file whose extension you want to change by browsing through your folders.
Make sure you know where your file is located. It’s like finding a book in a library; you need to know the section and shelf.
Step 5: Rename the File
Right-click the file and select "Rename" from the context menu, then change the file extension.
Be careful while renaming. Make sure to only change the part after the dot (e.g., from .txt to .docx), or you might end up with a corrupted file.
After completing these steps, Windows will prompt you with a warning about changing file extensions. Confirm your choice, and the file will now have its new extension.
