    AddSubFolders(rootNode, rootFolder);
}

public void AddSubFolders(TreeNode node, PSTFolder folder)
{ 
    List<PSTFolder> childFolders = folder.GetChildFolders();
    foreach(PSTFolder childFolder in childFolders)
    {
        TreeNode childNode = new TreeNode(childFolder.DisplayName + " (" + childFolder.ItemType.ToString() + ")" );
