VBScript to Delete Folder and all SubFolders with files

Here is the VBScript which will delete all Folders and Subfolders with even have files in it.
It took me so many hours to find this perfect script and all credits go to Rob van der Woude and the original script is here:
I just want to keep this for my reference and for everyone so that we all can save some time.

Option Explicit

Dim objFSO, objTempFolder, strTempFolder


Set objFSO        = CreateObject( "Scripting.FileSystemObject" )
Set objTempFolder = objFSO.GetSpecialFolder( TEMP_FOLDER )
strTempFolder     = objTempFolder.Path

DelTree strTempFolder, True

Sub DelTree( myFolder, blnKeepRoot )
' With this subroutine you can delete folders and their content,
' including subfolders.
' You can specify if you only want to empty the folder, and thus
' keep the folder itself, or to delete the folder itself as well.
' Root directories and some (not all) vital system folders are
' protected: if you try to delete them you'll get a message that
' deleting these folders is not allowed.
' Arguments:
' myFolder     [string]   the folder to be emptied or deleted
' blnKeepRoot  [boolean]  if True, the folder is emptied only,
'                         otherwise it will be deleted itself too
