Tips to Display File Extensions in Windows 10 for Better File Management
Making file extensions visible in Windows 10 isn’t complicated, but trust me, it really makes a difference when organising your files. When you can see those little suffixes like .txt, .jpg, or .exe, it gives you a quick heads-up about what you’re dealing with. Hiding extensions can lead to opening things you’d rather avoid, and it can throw off your workflow. To set this up, a simple tweak in File Explorer settings is all you need.
Getting Started with File Explorer
First off, find the File Explorer icon on your taskbar. It’s usually right there as it’s pretty popular. If it’s missing, click on the Start menu, type “File Explorer” into the search box, and it’ll pop up. Click to open it.
Accessing the View Settings
With File Explorer open, look to the top menu where you’ll see View. This is where you control how your files look. Here, you can turn on or off various options — including those important extensions.
Enabling File Extensions
In the View tab, find the checkbox labelled “File name extensions”. Click to tick it. Once activated, you’ll start seeing the file extensions next to filenames, making it easier to identify files at a glance. It’s especially handy for spotting file types before opening them.
Alternative Method: Using Folder Options
If you prefer another route or if things aren’t working as expected, try the Folder Options method:
- Open File Explorer, then click on View and select Options or Change folder and search options.
- In the Folder Options window, head over to the View tab.
- Uncheck “Hide extensions for known file types”.
- Click Apply and then OK to save your changes.
All Done! What’s Next?
Once you’ve turned on file extensions, close File Explorer — no restart needed, everything autosaves. Now, you’ll be able to see exactly what each file is without guessing. This is a big help for troubleshooting, organisation, and keeping your digital space tidy. Plus, you’ll feel a bit like a tech whiz.
Tips for Managing File Extensions in Windows 10
- Keep the File name extensions box checked so you don’t have to turn it on again.

- You can toggle this setting depending on what you’re working on.

Common Questions About File Extensions in Windows 10
What if I don’t see the “File name extensions” checkbox?
If it’s missing from the View tab, make sure your File Explorer window is fully expanded — it can hide options in small windows. Updating Windows might also help if some features are missing. And double-check that your settings aren’t globally hiding extensions, which you can verify in Folder Options.
Why are file extensions important?
Extensions give you a quick way to identify what type of file you’re dealing with. They help prevent accidental opens of malicious files and ensure the right program opens your documents or images.
Can I hide file extensions again if I change my mind?
Absolutely. Just uncheck the File name extensions box in the View tab, or check the box for Hide extensions for known file types. Easy as that.
Are file extensions the same across different operating systems?
Most common ones like .jpg, .txt, or .exe are standard across Windows, macOS, and Linux, but some are unique to certain OSs or software. It’s good to be familiar with them, especially when sharing files between systems.
How do I find out which program opens a certain file type?
Right-click the file and select Open with. You’ll see a list of compatible apps. If unsure, a quick online search of the file extension can tell you what program to use, or you can update default apps via Settings > Apps > Default apps.
Turning on file extensions in Windows 10 is one of those small tweaks that can save heaps of hassle. Knowing exactly what a file is helps prevent errors and boosts your security — especially when malicious files are everywhere these days. Plus, it just makes organising your digital clutter a lot easier. This quick fix might only take a few minutes, but it’s saved many from a headache or two in Windows.
Hopefully, this saves someone a few hours of frustration. It’s a solid tip that’s worked across multiple machines. Keep exploring — your tech skills will thank you.
