File extensions not showing in Windows 11?
By default, Windows 11 hides file extensions, which can make it difficult to identify file types—and in some cases, even put your system at risk.
If you’ve ever wondered why a file won’t open correctly or whether it’s safe to use, hidden extensions could be the cause.
In this guide, you’ll learn how to show file extensions in Windows 11 in under a minute, plus how to fix the issue if they are not showing properly.
How to Show File Extensions in Windows 11 (Quick Method)
The fastest way to enable file extensions is through File Explorer:
- Open File Explorer
- Click the View menu
- Select Show
- Check File name extensions
That’s it. File extensions will now be visible for all files.
For example, you will see file names like:
- document.txt
- image.jpg
- program.exe
Why You Should Enable File Extensions
Showing file extensions is not just about convenience—it’s also important for safety.
- Identify file types instantly
- Avoid opening harmful files
- Prevent file format mistakes
For example, a file named invoice.pdf.exe may look like a PDF, but it’s actually an executable file. If extensions are hidden, you might not notice the difference.
Enabling file extensions helps you avoid these risks.
