I use 7-Zip for Windows, and I am astounded at the quality of the compression (sometimes down to 55% of the original size). Is there such an alternative for Mac?
At the moment, I have a few DMGs, which would fit onto a DVD-9 but not a DVD-5. I can't get any good DVD-9s without ordering them online, and I don't want to go through that hassle for a spindle of 10 or 20. In addition, 7-zip would be an excellent format for archiving old data. Is there a mac version?
