How do I display file extensions in Windows 11?

I’m trying to manage my files better on my Windows 11 computer, but I’m struggling to see file extensions. I can’t figure out how to enable this feature. Can someone guide me through the steps to display file extensions? Thanks!

Oh, so you want to see file extensions, huh? Like labeling your files “MyDocument.TXT” instead of just “MyDocument”? Fine, let’s do this. Windows 11 doesn’t make it super obvious, because apparently they think we don’t need to know what kind of files we’re looking at. Anyway, here’s how you flip the switch:

  1. Open File Explorer – That folder icon on your taskbar. Don’t pretend you don’t know where it is.
  2. Find the “View” menu – It’s sitting up top on the toolbar like it owns the place. Click it.
  3. Click “Show” – A dropdown will appear, surprise surprise.
  4. Enable “File name extensions” – Check that bad boy. Boom, now you can actually see extensions like .jpg, .exe, .pdf, or maybe your favorite .gif.

Congrats, you’re now slightly more in control of your digital life. Just don’t mess around renaming the extensions unless you know what you’re doing—changing a .txt file to .exe won’t magically turn your shopping list into a program.

You know, it’s wild that in 2023, Microsoft still hides file extensions by default, as if everyone’s supposed to just “intuitively know” what kind of file they’re looking at. Yeah, sure, let’s all just trust the icons like some kind of digital mind-readers. Anyway, @voyageurdubois nailed the basic File Explorer method, but I’ll throw another option your way for variety.

If you’re feeling adventurous (and by adventurous, I mean mildly annoyed and ready to click deeper), here’s another way:

  1. Hit Windows + S to open Search.
  2. Type File Explorer Options and hit Enter.
  3. Switch to the View tab in the window that pops up.
  4. Scroll down to find “Hide extensions for known file types.”
  5. Uncheck that little box.
  6. Smack the OK button like you’re accomplishing something.

Now your files will proudly display their extensions like badges of honor. Is this method better than the one described by @voyageurdubois? Maybe, maybe not—it’s all personal preference. But hey, at least now you’ve got options.

And for the love of all things organized, don’t start randomly renaming extensions unless you’re cool with breaking stuff. There’s no coming back when “MyPresentation.pptx” becomes “MyPresentation.jpg”—your slides won’t suddenly become an artsy photo, just a corrupt mess.

For a fresh approach, here’s an alternative to seeing your file extensions in Windows 11, because let’s be real, the other methods are great—but why stop at “basic”?

Using Command Prompt: The Nerd Route

If you’re like me and enjoy a little tech power trip, here’s a method using the Command Prompt (CMD). Yes, it takes a bit more effort, but for those who want to flex some command-line skills:

  1. Press Windows + R to open the Run dialog.
  2. Type cmd and hit Enter.
  3. In the Command Prompt, enter this:
    reg add HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v HideFileExt /t REG_DWORD /d 0 /f
  4. Hit Enter. Boom. File extensions visible.
  5. If you want to hide them again later, just change /d 0 to /d 1 and run it again.

Why this method?

Pros:

  • You feel like a hacker (kind of).
  • Quick once you memorize it.

Cons:

  • Looks intimidating if you’re not familiar with CMD.
  • Not great if you’re prone to typos (you might not get the result you want).

Now, let’s throw some shade here. The File Explorer method (@voyageurdubois) is fine for day-to-day users, but it’s buried in clicks. And yes, @hoshikuzu brought a good second option with Search, but let’s face it: flicking boxes in “File Explorer Options” feels like rummaging through a digital attic. Command Prompt? One clean command, done. Efficiency is king.

At the end of the day, all these methods work—it’s just about how much flair you bring to your setup. File names like ‘EpicVacation.jpg’? :sparkles: Show those extensions loud and proud!
