SYMPTOMS
Microsoft Windows Explorer tree view may display a folder that does not have a name or that has an incorrect name after an external application creates a folder or renames a folder. This problem may occur with a namespace extension folder that is a junction point in the file system.

When Windows Explorer tree view handles a change notification for the shell from the external application, the change notification for the shell indicates that a folder has been created or has been renamed.



CAUSE
The files and the folders in the namespace extension are stored in the file system folder that is used to register the junction point. The SHChangeNotify function generates a file system ITEMIDLIST. This action occurs when the SHChangeNotify function is called by an application to notify the shell when a file system folder has been created or has been renamed. Windows Explorer tree view handles the change notification by passing the file system ITEMIDLIST to the IShellFolder interface of the folder that contains the item that is being created or modified. This action is performed to obtain the display name of the item. Change notifications for items under the junction point folder are not correctly handled. This problem occurs because the namespace extension expects to be passed an ITEMIDLIST that is generated by the namespace instead of by the file system folder.
