I've also used Flashget for downloading mass files before, as it's quite good for being used in automated ways.
Eg, I had a setup at a library - when computer starts up, Flashget starts minimized to system tray, and automatically starts downloading.  I also wrote a little program to hide Flashget's systray icon, so basically, Flashget was invisible, and downloading mass files XD


Anyways, just tried IDM - hmm, perhaps I haven't tried this one before - is this it?


If so, it's horribly under-featured in comparison to Flashget - I mean, you can't even control the number of parallel connections..
