I would like to add that FDM also does much more and it's worth checking out it's site to see:

http://www.freedownloadmanager.org/index.htm

Apart from the above features include:
-BitTorrent support
-Upload manager: easy way to share your files
-Flash video download and will convert .flv to more popular formats
-Remote Control
-Portable mode
-Preview audio/video files before download is completed and convert file format after download
-Splits files into several sections and downloads them simultaneously
-Site Explorer
-Adjusting traffic usage
-Simultaneous downloading from several mirrors
-Zip files partial download
-Active spyware and adware protection through active communication among users
-Multi language support
-GNU General Public License, ie open-source.

And it's site offers support and a forum for users too.
I've used this app for a fair while now and am still exploring it's possibilities. it integrates pretty cheerfully into Firefox.
