How to share partition to be accessed from IIS and store website media files inside it

I have a website that deployed on local machine on site and not accessed from Internet
the website use large media files , and the files are found on the same server but on other partition

I need to show these files in the browser but it can not be done until I add files inside intpub of IIS

is there a way to add the other partitions as shared to IIS and be able to access files from them
