After you’ve created files in your local and remote sites, you can synchronize the files between the two sites.
Before you synchronize your sites, you can verify which files you want to put, get, delete, or ignore. Dreamweaver also confirms which files have been updated after you complete the synchronization.
Click the Options menu in the upper-right corner, and then select Edit > Select Newer Local or Edit > Select Newer Remote.
In the Files panel, right-click (Windows) or Control‑click (Macintosh), and then select Select > Newer Local or Select > Newer Remote.
