Professional :: GetURL To Link To A Local Htm File?

Trying to set up a getURL to link to a local htm file, NOT a page on the internet. All the tutorials I have read tell me how to link to a file on the internet I'm trying to set up an intranet site for my training college where students can access training resources etc on the local network. Therefore my getURL needs to point to a local file, not one on the internet. I'm trying to link to a .htm file that resides on my computer. Does the htm file have to be in the same folder as the .fla file?? How do I do this?? I'm working on a Mac, Os X, MX 2004, if that makes any difference.
