How to Show File Extensions in Android and Windows 10

In this post, we’ll see how to show file extensions in Android and Windows 10. Let’s get started.

Show File Extensions in Android

By default, file extensions are shown in the default file manager (the one that comes with your Android device).

If you want to hide them, then here are the steps (In this instance, I’m using Android device running Oreo):

Open default file manager.

Hit the Hamburger icon (three vertical lines) at the top. Tap “Settings.”

Hit “Hide extensions” option.

Enabled Hide extensions option

That’s all. From now on, the file extensions will not be shown in the default file manager. In the future, if you want to show file extensions, then follow the above steps.

Show File Extensions in Windows 10

In Windows 10, most of the file extensions are hidden by default.

I said “most” because few file extensions such as .mui and .cpl are shown by default. You can see these file extensions within the “System32” folder of your PC.

If you wish, you can unhide hidden file extensions at any time you want.

Here, we’ll see two different ways to do this task. Let’s see what they are.

Method #1

Press Windows + E, and it will open “File Explorer” on your PC.

Click on “View” tab in Ribbon and then check “File name extensions.”

Open “File Explorer.”

Go to “View” tab in Ribbon.

Find and uncheck “File name extensions.”

Type the command “control folders” (without double quotes) and then press “Enter” key. It will open up “File Explorer Options.”

Find and uncheck “Hide extensions for known file types” which is between “Hide empty drives” and “Hide folder merge conflicts.”

Click on the “OK” button.

Follow the below steps to hide file extensions in Windows 10:

Go to “View” tab of “File Explorer Options.”
