To access to documents from UNC Windows routes

I have some documents pdfs UNC in a resource-type \server\folder$, to
whom it would log in to download from the application in Rails. The
server is different from where the application is housed. Is it possible
to gain access to these documents from Rails?

Or, only is possible to access to documents inside the program
folder?.

Thanks in advance
