Archive All / Export All. And I mean ALL documents I have stored.

Archive All / Export All. And I mean ALL documents I have stored.

How do I "select all" and then either "export all" or "archive all".  I don't mean just selecting the list of documents shown at a given time on the monitor, but all documents that I have.  I have seen this referenced as a "roadmap" item since 2007 but don't see a resolution or a way to do it in Zoho Docs.
