If you are working with different types of files on your Windows system, you may sometimes need to change the file extension. This simple guide will show you how to modify file extensions in Windows 10 safely and correctly.
What Is a File Extension?
A file extension is the set of characters that appear after the file name (for example: .txt, .jpg, .png, .docx).
Windows uses these extensions to identify the correct program to open the file.
Follow the steps below to rename or change any file extension on your Windows 10 computer.
Click on the Search bar and type File Explorer, then open it.
Navigate to the folder that contains the file whose extension you want to change.
At the top menu, click on View and make sure the checkbox File name extensions is enabled.
This allows you to see and edit the full file name, including the extension.
Right-click on the file and select Rename.
Modify the extension by typing the new one you want to use.
Windows will show a warning message stating that changing the extension might make the file unusable.
Click Yes to confirm.
You will now see the updated file extension, and the file icon may also change based on the new file type.
Changing file extensions in Windows 10 is quick and simple. Just enable file name extensions, rename your file, and confirm the change. Always ensure that the new extension matches the correct file type to avoid errors.
