If you are searching for a compression software or archiever then 7-Zip is the best one. It's open source and free. You can download it from here. I have used 7-Zip 9.18 beta in Win XP as well as in Win 7.
Just select Ultra from compression level and I prefer using .7z format.

I have myself tried it. I have compressed HALO game folder which is about 1.05Gb to just 338Mb using 7-Zip, which was previously compressed to 450Mb using WinRAR. One .avi format video of 1.81Gb was compressed to 434Mb.
7-Zip works in Windows 7 / Vista / XP / 2008 / 2003 / 2000 / NT / ME / 98. There is a port of the command line version to Linux/Unix.
