We have a SBS 2011 Server with Sharepoint 2010. All users connect to it as a mapped drive \\server\davwwwroot . Previously a document library was created for top level folders. A user has recently began creating folders through the mapped drive without creating a document library. These folders cannot be seen in all site content, and cannot be deleted (even as site admin). How can we get rid of these folders without restoring the site from a backup?
