how to get physical path instead of URL (OneDrive)

Hi!

I am writing a Word 2013 macro. I use ActiveDocument.FullName on a file in OneDrive (synced to my hard drive). I want to get a direct reference to my hard drive file name (c:\Users\User X\document.docx), instead of OneDrive UNC (https://d.docs.live.net/blaah/Documents). How can I get a physical filename/path in VBA?

Thanks,

Kaido
