Cyberduck Help / Synchronize Folders

Files can be synchronized by selecting the directory to synchronize in the browser and select File → Synchronize.

You will be prompted to select the directory on your computer to synchronize the files with. Cyberduck will only attempt to synchronize files that are of different size. Based on the modification date the file will be downloaded or uploaded from/to the server. You will be prompted to confirm the actions and if missing files should only be download, uploaded or mirrored.
