How to Hide and Unhide File Extensions on Windows 11/10?

What Are File Extensions?

File extensions are file types like audio files, video files, word files, and excel files. The audio file will only run on compatible audio software, as a video file will only run with video-compatible software.

File extensions are hidden on Windows computers by default. By seeing the file extension, you can easily tell which type of file it is. All file types will have different file extensions like .wav, .mp3, .wma, .docs, .XML, etc.


The operating system opens any file by understanding its extension and then decides which program can operate/open this file.
