Exporting PDFs using RIS format

Thank you for your help.  I’m trying to export my references using the RefMan (RIS) Export format in Endnote X4.  When I use this format, very few of the folder paths for my PDFs are transferred.  It seems that if a reference has a full text URL, it exports the URL instead of the folder path for the PDF.  Is there a way to change this behavior, since I would much prefer to transfer the links for my annotated PDFs?
