Well its basically a program that lets you download files at a much faster speed 

. It connects more then once I think and it downloads seperate parts of the file. At the end they connect eachother and you have one file 

.
It really works but the only bad part is that its a Trial version 

.
Its called IDM Internet Download Manager. 
You can get it at 
http://download.com
(also means it doesnt have any adware/spyware)
Also they have gotten many good reviews 

 I really recommend this

edit : Downloaded Adobe Photoshop 160 mb in 10 minutes 

 Something like that 

.
It lets you download at 290 kb/s And it doesnt change.
