importing attachments from papers

i am able to import a library with references from papers (apple), however i am not able to import the attachments.  Is there a way to import the referenced attachments to the correct folder in endnote?

I have the same question in reverse…

I would like to export a library from Win7 EndNote to MAC papers.  Creating an xml from EndNote seems like the answer, but this structure does not include attachments.  Using enlx seems like a solution, but papers can not use this extension.

Same problem, opposite direction.
