CAn someone tell me whats the BEST compression tool to cram a LOT of files into one small tight package. im talkin about compressing a 4 gb file into 2 or 1.5 gb (if thats even possile) or somethin similar; program strong enough to compress that much. I have winrar right now and its not reall compressing as good as i want it to. any advice would be great! Thanks!
