I'm exploring the use of Document Sets as a more managed approach to file handling (in the recordkeeping sense) in SharePoint.
The chief problem I have is that Document Sets are derived from Folders, and indeed it's possible to view Document Sets as a folder through Explorer View. But if I create a new Folder via WebDAV, it shows as a normal folder and not a Document Set. If I edit that folder's properties, I'm given the option to change the content type of the folder into a Document Set, but unfortunately this doesn't modify the behavior of the folder – to all intents and purposes it is still just a Folder despite having the other content type.
How can I prevent the use of Folders entirely in a Document Library? Alternatively, is there any way for a Document Set to be the default in WebDAV?
