Symbolic links in references not showing as 'clickable' X5


I store marked up notes, diagrams and PDFs in a directory structure in Windows. I would like to be able to link to those notes from within an End Note reference. When I copy (Shift - Right Click ‘Copy as path’) and paste the link into End Note the link does not display as a clickable link.

Is this a bug or something I am doing incorrectly?

Thanks in advance
