How to Display File Extensions in Windows 11

As an expert in tech-related issues, I, Tracy, understand the importance of being able to identify file types at a glance. In Windows 11, showing file extensions can help you avoid running potentially harmful files and makes it easier to manage your data. Here’s how to make Windows 11 display file extensions for all files.

Enabling File Extensions Through File Explorer

Step 1. Open File Explorer

Press the Windows key + E to launch File Explorer or click on the File Explorer icon on the taskbar.

Step 2. Access Folder Options

Click on the three dots icon (also known as ‘See more’) in the top-right corner of the File Explorer window. Select ‘Options’ to open the Folder Options dialog box.

Step 3. Show File Extensions

Under the ‘View’ tab, you’ll find a list of advanced settings. Look for the option “Hide extensions for known file types” and uncheck this box. Click ‘Apply’, then ‘OK’ to save the changes.

Note: This change will apply to all folders on your system.

Showing File Extensions Using the Folder View Menu

You can also control the visibility of file extensions directly from a folder window.

Step 1. Open View Options

Within an open folder or on the desktop, click on the ‘View’ dropdown menu in the File Explorer’s command bar.

Step 2. Check ‘File name extensions’

Within the expanded ‘View’ menu, find and click on the ‘Show’ submenu. This brings up options related to file and folder views. Here, simply check the ‘File name extensions’ option.

Why It’s Important to See File Extensions

Knowing the type of file you’re working with is crucial for several reasons:

  • Security: Certain file types can pose security risks, particularly executables like .exe, .scr, and .bat files that might be disguised as harmless files if extensions are hidden.
  • Differentiation: Some file names can be very similar or even identical. Showing the extensions can help differentiate between files, such as Word Documents (.docx) and Templates (.dotx).
  • File Management: For organizing and sorting files based on type, seeing the extension is incredibly helpful.

Troubleshooting File Extension Issues in Windows 11

Occasionally, you might encounter issues where the file extensions still do not show. Here are a few troubleshooting tips:

  • Make sure you have applied the settings correctly as described above.
  • Restart File Explorer from the Task Manager if the changes do not seem to take effect immediately.
  • Ensure your system is up to date with the latest Windows 11 updates, as these can sometimes resolve unexpected issues.
