In the browser, select the files tab. Now, choose "desktop" and then drag your tracks directly to the desktop folder in the browser, and there you go! Your track will appear on the desktop. I drag tracks out to clients all the time, when I do work as a session musician. For example, I have dropbox folders with several clients. What I do is I drag in their rough mix for me to play to, I cut my track, then I print my track via CMD/CTRL+B and then I drag the track to the client's dropbox folder. Off it goes!
Hope that helps show you that this can already be done in Studio One.
