Where does non-SharePoint content saved via WebDAV end up? If I use the Windows Explorer to open any site in SharePoint, I can create a folder using the Explorer and add files. But these files aren't visible to SharePoint as far as I can see.
If I add files to existing document libraries, I know everything works as if I had added the file via SharePoint.
Are these files part of the content database?
Are these files included in SharePoint Exports and SharePoint Backups?
Is it perhaps even disrecommended to store files this way?
