If you have a cineSync Pro account, you have the option of adding Aspera file transfer functionality to cineSync. Aspera gives you much faster and more reliable file transfers using your existing network than any other available file transfer option. If you're moving large files regularly, it's worth considering Aspera. More information on how Aspera works is available here.
Once the Aspera component has been added to your account, you can use it to transfer files the same way as you would use ftp, http, etc.
