WinZIP and StuffIt Expander compatibilities
I recently became a fan of some of the new compression algorithms that WinZIP is supporting. The one that is working best for me is PPMd. I was able to get about 40% compression on my camera RAW files, about 100GB and reduce that to about 60GB. This was a huge savings and allowed me to avoid a hard drive upgrade possibly for six more months.
I wanted to send a large PDF to friends and I know some of them use a Mac, so I was curious to see if StuffIt expander supported this compression algorithm. As it turns out, 10.x does not, but 11.02 does.
It’s funny, I’ve been seeing a reminder lately on my MacBook asking me to upgrade to 11.02 and I kept hitting, no, no, no. Then, when I tried to unpack my ZIP file that uses PPMd compression and saw how 10.x failed, I immedately upgraded and was pleasantly surprised to see the zip file unpack successfully.
