Assume that you map a network drive from a computer that is running Windows 8, Windows Server 2012, Windows 7 Service Pack 1 (SP1), or Windows Server 2008 R2 SP1 to a Web Distributed Authoring and Versioning (WebDAV) shared folder. Then, you try to perform a drag-and-drop operation to replace a folder in the WebDAV shared folder. However, the operation fails. Additionally, you receive the following error message:
Error 0x80070091: The directory is not empty.
