When working with Dreamweaver for the first time, or on a new website for the first time, you need to define the site so that Dreamweaver can work with it. This process includes naming the site, placing the local files on a directory on your hard drive, and showing Dreamweaver where those files will be published on the web. Follow these easy instructions to define a new website in Dreamweaver.
First, you should go to the “Site” menu and choose “Manage Sites.”
As you can see from the screen shot, this will open a dialog window. Choose “New Site” from the “New” button.
