Once you have files in your local and remote sites, you can synchronize the files between the two sites. Dreamweaver can help you keep track of what updated files need to be moved to your remote server and what updated files you need to get from your remote server using the synchronize command.
how to use synchronize
In the Files (Assets) panel, click on the Files tab (if not already selected).
Click the Options menu in the upper right corner of the Files panel, and select Site > Synchronize. The Synchronize Files window will open.
From the Synchronize drop-down menu, select the desired option.
From the Direction drop-down menu, select the desired direction.
Click the Preview button. A report window will open displaying what files need to be updated.
Click Update.
When the synchronization is complete, click Done to close the window.
