How to Show File Extensions in Windows 11

Windows 11 supports almost all file types, provided it has the appropriate apps to open those files. For example, the built-in Photos app of Windows 11 supports JPG, PNG, JPEG, and other image file formats. Similarly, you would need dedicated apps to open different file formats on Windows.

While it’s pretty easy to download files from the internet, sometimes, you may end up downloading files that your PC can’t read. To open/view such files, you first need to identify the file extension and download a dedicated app.

You can view the file extension by right-clicking on the file and choosing properties. The properties page would list all details of the files, including the file extension. However, if you don’t want to check the extension manually, you must configure Windows 11 to show file name extensions by default.
