You should be able to run a workflow on the originating document that would copy the document to the source destination. This can be achieved by using the "Copy Document" workflow action. Just configure the destination source to point to the library you want to move the file to.

Also see the attached example workflow which you can import and use. Download the file and change the extension from .zip to .nwp and then import.

This does not work.  you have to move the the document out of the folder.  before the workflow runs

thanks
