The most fundamental setting for any script is the locations it should synchronize. You can configure them in the “Locations” area of the settings. You can also use the “Archive” area of the settings to configure a location to hold old versions of files as they're replaced or deleted.
Most scripts involve at least one location on your computer, either from the internal hard drive or an external USB or Firewire drive.
If a folder you want to synchronize is on another Mac you control running Mac OS X v10.6 Snow Leopard or later, SynkSharing is the best and easiest way to synchronize with the remote machine.
If the computer on which the folder you wish to synchronize is located is not a Mac, isn’t running Mac OS X v10.6 or later, or you don’t have administrator privileges on it, you can still synchronize with it using traditional file sharing.
