If they're hosted on a standard web server you can start multiple WebRequests (or FtpWebRequests, if they're on an FTP server). I recommend putting all the file names onto a shared queue and having one or more (probably about 4) worker threads that repeatedly take an item off the queue, create and run a download request until there are none left. Those workers can fire events that the UI can pick up to update a display.

You want more than one thread because otherwise there is always wasted time in between one request finishing and the next starting when your bandwidth is not being used. Somewhere between 2 and 5 seems to be the default in FTP clients which have a similar requirement.
