Best And Free Download Manager for Rapidshare, MegaUpload and More

I was so happy to find this extremely helpful piece of software for direct downloading/http downloading from web servers like Rapidshare, Megaupload and more !.Often we download games, movies and songs from these website with given set of URL's where larger files are split into smaller pieces with archives in famous Winrar format. My apologies if your are web police but here we talk about masses.
