Dreamweaver comes with built-in FTP functionality, which is nice because you don't need to have a separate FTP client to upload your document files to your Web server.
Dreamweaver assumes that you will have a duplicate of your Web site structure on your hard drive. So in order to set up a file transfer setting, you need to set up a site in Dreamweaver. Once you've done that you'll be ready to connect your site to a Web server using FTP.
Dreamweaver also offers other methods to connect to Web servers, including WebDAV and local directories, but this tutorial will take you through FTP in-depth.
