Zipeg is free Macintosh utility for Mac OS X. Zipeg allows you to open and explore content of zip, rar and other archives, preview files and images before you extract/unzip them. Extract only the files you want. Pictures come to your mailbox as zip archives? Zipeg allows you to decide what do you want to extract. You can choose what to extract and where to put extracted files or just drag and dropthem. This is safer (browse before extract) and more intelligent way of zip archives handling.
