[singlepic=33,,,,left]"ZipGenius is the absolutely free software for Windows® that lets you compress files to almost any kind of archive. ZipGenius supports more than 20 compressed archive formats, including CD/DVD-ROM image files in ISO9660 standard. This is the file compression suite you were searching for: it is free and easy to use, plus it supports more than 20 formats of compressed archives, including RAR, ARJ, ACE, CAB, SQX, OpenOffice.org documents and the excellent 7-zip. ZipGenius now can precompress executable files going to be added to a ZIP archive through the UPX compressor."
I started using this program in November when I needed a free yet robust program for unzipping a lot of different file types at work. Not ONLY does this program do what I wanted it to - it far surpassed my expectations. You have the standard abilities to export files where you want and in seperate folders. You have the ability to recompress groups of files. There is just so much this FREE program offers that it's pointless to waste time on the "big names" of compression like WinRAR or WinZip (do they even still exist!?).
Do yourself a favor ... go and download. After all - it's free!
