If you’ve ever been baffled by file extensions—or rather, the lack of them—while navigating through Windows 10, you’re not alone. It can be tricky to differentiate between files when you can’t see their types. Fortunately, it’s a breeze to set up Windows 10 to always show file types. This article will walk you through the simple steps to display file extensions, ensuring you never mistake a .docx for a .pdf again!
How to Show File Type in Windows 10
Showing file types in Windows 10 involves a few straightforward steps that will allow you to see the extensions of your files, such as .txt, .jpg, or .mp4. This can help you quickly identify the file format and avoid any confusion or mistakes when opening or editing files.
Step 1: Open File Explorer
Launch File Explorer by clicking the folder icon on your taskbar or pressing Win+E on your keyboard.
File Explorer is your main hub for all files and folders. You’ll need to be in here to access the settings we’ll be changing.
Step 2: Go to the View Tab
Click on the "View" tab located at the top of the File Explorer window.
This tab contains various viewing options for your files and folders, including the one we need to find.
Step 3: Check the File Name Extensions Box
Locate the "File name extensions" checkbox and click it to enable it.
By checking this box, you’ll start seeing the file extensions next to the file names throughout Windows Explorer.
Step 4: Apply Changes
The changes will apply automatically, so you don’t need to do anything extra.
Windows 10 will now display file types in all your folders, making it easier to identify and manage files.
Completing these steps will instantly reveal the file types for every file in your File Explorer. You’ll see the extensions appended to the file names, which makes it easier to identify what type of file you’re dealing with, be it a .jpeg image or .mp3 audio file.
