How to Show File Extension in Windows 11

File Extensions make it easy to identify the file type at a glance. Here is how to turn on and show file extension in Windows 11.

Even after all these years, Microsoft still hides the file extensions for known file types. If you are wondering, file extensions are nothing but a few characters that you see after the file name followed by a period. Every file type has its own extension in Windows. For example, text files have .txt extension, Word documents have .doc or .docx extension, etc. When creating new files, you must add a proper extension to be opened or executed properly.

As you can guess, file extensions make it pretty easy to identify the file type at a glance.

As with previous versions, Windows 11 too hides the file extension by default. Though not a big deal in the grand scheme of things, showing the file extension is pretty useful. Personally, it is one of the foremost things I do after installing Windows 11.

So, without delay, let me show you how to show file extension in Windows 11.
