For the 6hours constraint:

I need an example as to how to sync files from the server to local machine. The only files I want are those that are 6 hours or greater from the time of sync. A sync is going to be done every 6 hours to bring all files since the last sync down to the local server. Please assist. I have a script that I am doing this from being called from a batch file.
