I haven't used dreamweaver for some years but I believe it has a built in ftp function or you could use one of these [webmasterworld.com].
The syntax is ftp://username:password@www.yourdomain.com
Once you have opened the directory you can then then drag the address to your favourites. That way you cn then click on the link like any other bookmark.
Then just copy and paste your files to the directory like you would moving files on the local C drive in windows explorer.
