Create Simple Script to Show / Hide File Extensions in Windows XP, Vista and 7

Recently we posted a tutorial about creating script to show / hide hidden files and folders in Windows: Create Simple Script to Show / Hide Hidden Files and Folders in Windows XP, Vista and 7
Today in this tutorial, we are going to share another similar script which can be used to show / hide file extensions in Windows.
This script when executed, checks the status of "Hide extensions of known file types" option and toggles its value. So if its set to hide file extensions, it changes the option to show file extensions and vice versa.
Simply copy paste following code in NOTEPAD and save the file with name "Show_File_Extension_On_Off.vbs" (including quotes):

FileExt = "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\HideFileExt"
Set Sh = WScript.CreateObject("WScript.Shell")
St = Sh.RegRead(FileExt)
If St = 1 Then
Sh.RegWrite FileExt, 0, "REG_DWORD"
Else
Sh.RegWrite FileExt, 1, "REG_DWORD"
End If
Sh.SendKeys("{F5}")

That's it. You can place this script at any location like Desktop, Quick Launch toolbar and whenever you need to toggle the "Hide extensions for known file types" option, simply run the script.
PS: If you don't want to create the script manually or face any problem while creating the script, you can download a ready-made script using following link:
