By default, and as a consistent design decision going back to previous versions, the Windows 11 File Explorer hides file name extensions. Though it simplifies the interaction between a casual user and provides a cleaner user interface, there are advantages and most would like to have file name extensions to be shown. Being able to verify actual file name extensions gives users better recognition and control over their files, from being able to quickly spot disguised executables ( e.g. invitation.pdf.exe ) and avoid malicious software being run or installed on their machines, to having better control when working with different types of files, like when viewing files that have similar or the same names ( e.g. image.jpg and image.png ). Visual cues like icons are not as reliable as actually knowing the file name extensions of the files that we manage and work with.
Below are 2 ways to enable file name extensions to be shown in Windows 11 File Explorer.
View options in File Explorer ( Quickest Method )
- Open File Explorer ( Windows Key + E )
- On the toolbar, click on View -> Show -> File Name Extensions. File Name Extensions should have a checkmark after being selected or clicked.
- Filename extensions should now be displayed and shown in File Explorer.
Folder Options ( Traditional Method )
- Open File Explorer ( Windows Key + E )
- Click the three-dot menu and select Options
- In the Folder Options dialog, open the View tab
- Under Advanced settings, look for and uncheck the setting for Hide extension for known file types.
- Click Apply and then OK.
