Showing or hiding file extensions in Windows 11 lets you see those little dots and letters at the end of filenames, like “.txt” or “.jpg”. These extensions tell you what kind of file it is and which program opens it. For example, a photo might show as “Holiday.jpg” instead of just “Holiday”.

By default, Windows 11 hides these extensions to keep things tidy. However, showing them, like “.exe” for programs, can help you avoid mistakes. Renaming a file extension by accident could stop the file from opening.

You can easily change this setting in the File Explorer’s View options.

⚡ Quick Answer

Open Settings, navigate to System > Advanced > File Explorer, and toggle on “Show file extensions.” This simple adjustment displays the file type, like .docx or .jpg, directly in File Explorer.
