How To Show File Extensions in Windows 10

When you open a document in Windows 10, you may notice that it is not categorized properly. Document files do not show the file extension. This can make it difficult for you to know what type of file it is or what program can be used to open them. Luckily, there is an easy way to display file extensions in Windows 10.

This method works in both the File Explorer and the various apps that create file types. Let’s take a look at how to show file extensions in Windows 10.

How to Show File Extensions in Windows 10

You can easily show file extensions in Windows 10. This can be done from File Explorer, from the Windows 10 apps that use this file browser, or via PowerShell. Let’s discuss each method separately.

Method 1: Show File Extensions in File Explorer

The quickest way to show file extensions in Windows 10 is from File Explorer. Simply right-click a file and select ” Properties ” from the menu. Then, under the ” Details ” tab, check the box next to ” Show file extension “.

This option is available for all file types, not just those from Microsoft. However, this method only works in Windows 10.

Method 2: Show File Extensions in Windows 10 Apps

There are many apps that create document type file extensions, such as Microsoft Word, PowerPoint, and Excel. If you are using one of these apps, you can easily show the file extension.

Open the file in the app. Press the Windows + I keys on your keyboard, or open the Windows Settings app and select ” Applications “. From there, select the app you want to open, and then select the ” Options ” button. From there, select the ” General ” tab and check the ” Show file extensions ” box.

Method 3: Show File Extensions in PowerShell

PowerShell has a built-in way to show file extensions. This method is a bit more work, but shows the file extension for all files on your computer.

First, open an administrative command prompt. Next, type the following command and press Enter:

Get-ChildItem -recurse -filter ‘.exe’ -exclude ‘dat‘ | Foreach-Object {



Method 4: Show File Extensions in Command Prompt

If you prefer a command-line method, you can use the following command to show file extensions in Command Prompt:

type %PROGRAMFILES%\WindowsApps\ \word\vc\vc.exe %PROGRAMFILES%\WindowsApps\ \office\office.exe %PROGRAMFILES%\windows\balloon\launch.exe %PROGRAMFILES%\windows\explorer\explorer.exe


Showing file extensions in Windows 10 is an easy and effective way to protect yourself from keylogging and other kinds of spying. This is because it prevents strangers from viewing your documents without your consent.

We recommend that you change the file extensions for all of your documents to hide their file types. Doing so will prevent strangers from knowing what you are working on, saving, and planning to do.

Keep in mind that a quick way to show file extensions in Windows 10 does not work on a long term basis. This is because Windows 10 updates are constantly changing the ways that files are organized. Moreover, the file types may change over time as well, which means that the method may become less effective over time.
