How to Show File Extensions in Windows 11 (Beginner-Friendly)

showing-files-with-extensions-visible.png

File extensions (like .txt, .docx, .exe) tell Windows what type of file you're opening. By default, Windows 11 hides these extensions to keep the interface clean.

But hiding file extensions can cause confusion—for example, you might mistake a "document.exe" file (a program) for "document.txt" (a text file). Showing them helps you identify files easily and avoid mistakes.

In this guide, you'll learn how to show file extensions in Windows 11 in 2 simple ways. No extra tools, no risky changes.

Method 1: Show File Extensions via File Explorer (Easiest)

  1. Open File Explorer (press Windows + E shortcut or click the folder icon on the taskbar).
  2. At the top of the File Explorer window, click the View tab.
  3. In the "Show/hide" section (on the right side of the View tab), check the box labeled File name extensions.
  4. That's it! All files will now show their extensions (e.g., "notes.txt" instead of "notes").

Method 2: Show File Extensions via Folder Options (Alternative)

This is another way to enable file extensions, which works for all versions of Windows 11.
  1. Open File Explorer and click the View tab.
  2. Click the small arrow next to Options (on the far right of the View tab) and select Change folder and search options.
  3. In the Folder Options window that pops up, go to the View tab.
  4. Scroll down the list of "Advanced settings" and uncheck the box that says Hide extensions for known file types.
  5. Click Apply and then OK to save the change.

How to Hide File Extensions Again

If you want to hide extensions later, just reverse the steps:
  • For Method 1: Uncheck "File name extensions" in the View tab.
  • For Method 2: Recheck "Hide extensions for known file types" in Folder Options.

Why Should You Show File Extensions?

  • Avoid opening harmful files: Malware often hides as harmless files (e.g., "photo.jpg.exe"—hiding the .exe extension makes it look like a regular image file). Showing extensions helps you spot these risks easily.
  • Organize files better: Knowing the file type (e.g., .pdf vs .docx) helps you sort and manage your files without opening them.
  • Avoid renaming mistakes: If you rename a file without seeing the extension, you might accidentally change it (e.g., renaming "report.docx" to "report.old" is fine, but renaming it to "report" without the .docx extension can break the file).

Important Note

Showing file extensions is safe and won't affect your system. It's a simple setting that makes using Windows 11 more convenient and secure, especially for beginners.
That's all. Now you can easily see file extensions in Windows 11 and use your files more safely.
