How to Show or Hide File Extensions in Windows 11 File Explorer
You show or hide file extensions in Windows 11 by toggling a setting in File Explorer’s View options.
File extensions are the suffix after a filename, such as “.txt” or “.jpg”, that identifies the file type and the application needed to open it.
For instance, a document might be saved as “Report.docx” or a photo as “Vacation.png”. By default, Windows 11 hides these extensions.
Showing extensions, like seeing “.exe” for executable files, helps you avoid accidentally changing a filename’s extension and making the file unopenable.
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.
