3rd Party Storage Services (e.g., Dropbox, Amazon S3, Microsoft OneDrive, Google Drive, Box, Rackspace, etc.) are mountable and un-mountable using an asynchronous operation (in prior releases, this was a synchronous operation). Once mounted, these 3rd party folders function like any other WebDAV resource. This kind of WebDAV collection (a "Dynamic Extension Resource Type" or "DET" for short) can also be designated as an LDP Container, making Virtuoso WebDAV a powerful LDP proxy mechanism for storage services that do not currently support LDP.
