The server parameters are set in Configuration: FTP File Transfer > Servers.

Progressive Download

A WM Appliance configured with a hard drive also supports progressive download. Progressive download (or On Demand Playback) is a method of delivering audio and video that involves caching and playing the downloaded portion of a file while a download is still in progress via FTP.
