If You Cannot View And Edit File Extensions In Windows 11, It Is Because The Option To Show Extensions Is Not Enabled By Default, And You Need To Enable It.

The file extension specifies the type (format) of the file you are dealing with. A file extension helps the operating system identify programs supporting a particular file format. When a user clicks on the file, it will be opened with the specified program. While the file extension affects the program that opens the file, it also determines its icon.

By default, Windows does not display the extension of recognizable files in the file name; Therefore, the file format cannot be recognized, or its extension can be changed. If you haven’t installed a program that can open a specific file format, this file will be unknown in Windows until you install the required program.

If you ever need to change the file extension (for example, a file that can be opened in compressed archive format), you should turn on the option to show the file format in Windows. This article will describe three ways to do this in Windows 11.
