Yes, i'm using winrar only because WinZip can't support .rar files, and most of cracks for todays games are in *.rar files.Also, there is a *.tar support, which is needed for those who mess with hosting pachages and there are themes for some portals, forums etc. in this file format.May i sugest TugZIP, which is something like WinRAR, but it's not shareware but freeware. It is quite fast for a compression tool. Free download here http://www.tugzip.com/
