Managing file extensions in Windows 11 can be essential for both security and organization. Showing file extensions helps you easily identify file types, which is useful when verifying downloads or preventing file spoofing.

What You’ll Need
- A Windows 11 PC with administrative access (recommended but not strictly necessary)
- Basic familiarity with navigating Windows settings and File Explorer
Step-by-Step
- Open File Explorer by clicking the folder icon on the taskbar or pressing Windows + E on your keyboard.
- In the File Explorer window, click on the three-dot menu (More options) in the toolbar at the top, then select Options from the dropdown menu. Alternatively, you can access Folder Options via the Control Panel.
- In the Folder Options window that appears, switch to the View tab.
- Scroll through the list of advanced settings until you find the option labeled Hide extensions for known file types.
- To **show** file extensions, **uncheck** this box. To **hide** file extensions, **check** this box.

- Refresh your File Explorer window (press F5 or reopen it) to see the changes in effect.
Common Mistakes
- Forgetting to click Apply after changing the setting.
- Modifying the setting in the wrong Folder Options window—ensure you’re in the correct view (Windows 11’s File Explorer options).

- To quickly access Folder Options, press Windows + R, type control folders, and hit Enter.
- Be aware that some applications or system files may have restrictions on changing their extensions or visibility.
- If you hide extensions, be cautious with file names to avoid accidentally overwriting or corrupting files.
Troubleshooting

- Close all open File Explorer windows and reopen them to refresh the view.
- Ensure you clicked Apply and OK after changing the setting.
- Restart your computer to ensure settings are properly refreshed.
- Check if your user account has the necessary permissions to change system settings.
