How to Change, Hide or Show File Extension in Android

In this post, you will see:

Let’s get started.

How to Hide or Show File Extensions (Android)

The Files app that comes with the Android device always displays file extensions.

It does not have the ability to hide file extensions.

The same applies to Mi File Manager, Solid Explorer, and File Explorer Root Browser.

Show or Hide File Extensions in Astro (Android)

You can hide or display file extensions for individual or all folders in Astro.

Remember that all folders setting doesn’t override the single folder setting.

With that said, let’s see both.

All Folders

Tap the three vertical lines at the top left.

Click on “Settings” in the menu.

Tap the “Set Default View Settings” option.

Check (to show) or uncheck (to hide) “Show file extensions.”

Note: If the above settings do not work in the folder, follow the steps above (1 to 3) and hit the “Clear” button beside “Clear Directory Options.” Remember that this will clear custom directory settings.

Single Folder

Open the folder.

Tap the three vertical dots at the top right.

Click the “View Settings” option in the menu.

Navigate to the “Advanced” tab.

Check (to show) or uncheck (to hide) the “Show file extensions” option.

Press the “Ok” button at the bottom.

How to Change the Android File Extension

Open the Files app and tap “Browse” if you are not yet in it.

Scroll down and press “Internal Storage” or your SD card.

Now find the file for which you want to change the extension.

Press this file long and then press the three vertical dots at the top.

Tap “Rename” and in the pop-up you will see the file name, a dot and the extension of the file.

Remove the existing extension and then enter the desired extension.

Press the “OK” button and tap “Rename.”
