Change the current folder to the one given in parameter throws ArgumentNullException if the argument was null

Use the FullRefresh method if you want to refresh a ShellTreeView. All expanded branches of the file system structure will be refreshed. If you just want to refresh one node and its child nodes, use the RefreshNode(ShellTreeNode, Boolean, Boolean) method.
