Using MS Word 2010, when opening an existing document from a network drive, an "owner file" is created on the drive. This "owner file" is in the format ~$nnnnnnn.doc, is 1kb in size, and contains the UserID of the person who has the file open. Upon exiting the MS Word session, the owner file should auto-delete, but it does not. This tends to clog up the network share, and can lead to false indications of the file being open by someone else. As far as I can tell, this is unique to MS Office 2010 (we never had the problem before upgrading to Office 2010. How can this be corrected so that the "owner files" will automatically delete when exiting Word 2010?
