How to Display File Extensions in Folders in Windows 7 & Above

In Windows 7 and above, files within folders appear with a name beneath the icon, but without the file extensions. While the icon will show the user what file extension each document has, some users prefer to have the file extension visible on every file. This is ideal for people who have folders full of files that have the same icons as a result of being opened in the same applications, but which have different extensions.

How can I display file extensions in folders on Windows 7 (or later)?

I can’t find it since I upgraded from WinXP.

Users who have upgraded from Windows XP can make file extensions visible in folders two different ways. If you are unable to use method 1, move on to method 2 which is exclusively for Windows 8 users.

Method 1: Folder/File Explorer Options

The first method is to open Folder Options in Windows 7 and 8, or File Explorer Options in Windows 10.

  1. Hold the Windows Key and Press R.
  2. In the Run dialog, type C:\Windows\System32\rundll32.exe shell32.dll,Options_RunDLL 7 and Click OK.
  3. Scroll down in Advanced settings and look for Hide extensions for known file types. If files in your folders do not appear with a file extension, then this option will be checked. Click it to uncheck it, and then press OK

Method 2: Change Settings in File Explorer Ribbon

For Windows 8 and above users, it is possible to view file name extensions by changing settings in the folder’s ribbon.

  1. Open File Explorer from your taskbar or Start menu.
  2. At the top of File Explorer you should see File, Home, Share, View and Click the View tab from this ribbon.
  3. In the settings that appear below the ribbon, you will see three check boxes. Beneath the Item check boxes check box, you will see File name extensions. Click this check box and exit the window.
