Delete Folders

including subfolders

This script deletes folders, empty or not, all in one go, like DOS' DELTREE command does.

 

DelTree
VBScript Code:
Option Explicit

Dim objFSO, objTempFolder, strTempFolder

Const TEMP_FOLDER = 2

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
