Dreamweaver 4, templates, moving nested index.html to primary

I downloaded a free template for use in DW CS4.  I see the index.html nested a couple of folders down.  I can open the template, and edit it, but of course when I publish to my web server, my index.html is still nested.

How do I make that index.html nested down two folders deep become my default home page so that when my users type www.mydomain.com, my site will load the nested index file?

thanks
