Erm, one of the main features of Dreamweaver, including previous versions, is to define your site.
I'm only using v6.0 and I set up my site properly using DW's wizard. Once that's done, a simple Syncronize click updates everything on your site. Everything.
So, right-click on on your site name, select Syncronize, and hit Yes to define your remote server. Job done. fini
