Easy-GZ is a compression tool which allows extremely tight compression and quick decompression. Based on the GZip standard and optimized for the Macintosh platform, an easy-to-use, effective GZ compressor has finally been brought to the Mac OS. Is this software free or not? I’m putting it in the free category - if you find out otherwise please send me an email.
