How to Show or Hide File Extensions in Windows 11 File Explorer
You can show or hide file extensions in Windows 11 File Explorer by adjusting a single setting.
File extensions are the dots and letters at the end of a filename, like .exe or .txt, which tell your PC what type of program to use to open that file.
For example, you might see .docx for Microsoft Word documents or .jpg for images. In Windows 11, these are hidden by default.
Enabling file extensions can prevent accidental renaming of files, which could make them unusable.
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.
