Dreamweaver helps you organize the files in your local and remote sites. It allows you to easily duplicate the structure of your local site on a remote server, or to duplicate a remote Web site's structure on your local system. The relative links that you create on your local site continue to work after you transfer files to the remote site, because the structure of the two sites is identical.
You create a local site in Dreamweaver by creating a local root folder for the site (or by making an existing folder into the local root folder), using the New Site command; see Creating a local site. You then associate your local site with a remote server using the Define Sites command; see Associating a remote server with a local site.
When you transfer files between local and remote sites, Dreamweaver maintains parallel file and folder structures between your local and remote sites. If needed folders do not yet exist in the site that the files are being transferred to, Dreamweaver automatically creates those folders. You can also synchronize the files between your local and remote sites; Dreamweaver copies files in both directions as necessary, and optionally removes unwanted files as appropriate.
Dreamweaver includes a number of features for structuring a site and transferring files to and from a remote server. To make collaborative work on a Web site easier, you can check in and check out files on the remote server; others can then see when you're working on a file and know not to edit that file at the same time. (Note, however, that Dreamweaver does not perform version control.)
