Showing file extensions in Windows 11 can feel like a basic thing, but honestly, it’s pretty crucial if you want to avoid opening the wrong files or falling for some sneaky malware. The process is straightforward — just a couple of clicks — but because Windows likes to hide these settings in weird places, sometimes they get turned off without most folks realizing it. So, if you’ve ever accidentally opened a file with an unexpected extension (like opening a.exe that looks like a.txt), then revealing those extensions might be a game changer for your workflow and security. Once visible, it’s easier to differentiate between similar filenames, and it helps with troubleshooting when files won’t open properly.
How to Show File Extensions in Windows 11
Alright, here’s the deal. This guide will walk through the steps to get those file extensions shining through, so you can finally tell a.zip from a.rar or a suspicious.scr from a legit.pdf. It’s pretty much a settings toggle, but Windows makes you dig a tiny bit for it.
Go to the File Explorer and open its options
- Fire up File Explorer by clicking the folder icon on your taskbar or just press Win + E.
- Once it’s open, click on the three dots menu in the top toolbar — that’s the “More options” button — and select Options. Sometimes it’s called Folder Options or File Explorer Options depending on your setup.
- This pops open a window, and you want to go to the View tab. Not the “General” one, but “View” — it’s usually right next to it.
Now, you’re inside the settings, and the real magic happens here.
Turn on “Show File Name Extensions”
- Scroll through the list or look for a checkbox labeled Hide extensions for known file types.
- Uncheck that box. Yep, just click that checkbox to turn it off.
- Click Apply and then OK to save the changes.
And that’s pretty much it. If you follow these steps, your files should now display their extensions right in File Explorer. It’s kind of weird how Windows hides this setting by default, but once you’ve turned it on, it’s hard to go back without feeling blind.
Tips for Showing File Extensions in Windows 11
- Always double-check before opening download files — seeing the extension can tell you if it’s legit or not.
- Getting comfortable with common extensions (like.docx, .mp4, .exe, .bat) can save a lot of headaches.
- Keep in mind, you can toggle this setting anytime if you decide you don’t want to see extensions—just go back into the options and check/uncheck the box.
- On some setups, the settings might reset after big updates, so if it’s not staying enabled, check again or tweak the Group Policy or Registry settings.
Frequently Asked Questions
Why should I show file extensions?
Basically, it helps you tell what kind of files you’re dealing with—important for security (avoiding malware) and managing files efficiently. Seeing extensions helps prevent foolery, like opening a dangerous script that looks like a document.
Can I hide extensions again if I change my mind?
Yeah, just revisit the same steps and check that box labeled Hide extensions for known file types. Windows will hide them again — easy peasy.
Does showing extensions slow down my PC?
Nope. It’s just a visual setting, no impact on performance. It’s like turning on labels on your files; it doesn’t affect how the files open or how fast your system runs.
What if I don’t see extensions after turning them on?
Try restarting your File Explorer (right-click the taskbar icon and select Restart) or just reboot your PC. Sometimes Windows gets a little lazy about applying changes immediately.
Any risks to showing file extensions?
Not really. It’s just a display setting, but it can help prevent opening the wrong files or falling for phishing attempts. Of course, speed reading extensions isn’t foolproof—but it’s definitely useful.
Summary

Wrap-up
Getting those extensions to show isn’t some complicated hack — it’s just hidden behind a menu full of other options, which makes sense because Windows loves to hide the good stuff. But now, with a few clicks, your files are way easier to sort and identify. Especially if you’re someone who downloads a lot of stuff, being able to see extensions clearly can save a lot of trouble down the line.
Not sure why it took so long to figure out, but anyway — hopefully this shaves off a few minutes for someone. Just remember, it’s a quick tweak that can make your file management way safer and smarter.
