How can I easily update my local files with remote files that have been edited online?

Since this is not Contribute, I'm not seeing anything in the DW CS4 reference about how to easily have DW check for the most recently edited files on the server (edited by clients), so that these can be downloaded to my DW site locally.  Does anyone know of a way to do this, besides checking the modification dates on the remote files and downloading them that way?

Thanks,
