I like to put my Local Site inside my Local Testing server's default web directory.
On wamp, the directory is www.
C:\wamp\www\MySiteFolder\
On Xampp and Mamp, the directory is htdocs.
C:\xampp\htdocs\MySiteFolder\
When I save work locally in DW, it's automatically saved on my Testing Server so previewing in browsers is seamless. No temp files required.
http://localhost/MySiteFolder/index.php
Hope this helps.
