"I could not imagine a computer life without StuffIt. I work a lot with media and music libraries for multimedia production and organize my huge amount of audio samples with StuffIt libraries. In no time it is possible to organize pack or unpack these samples using stuff it. The best really is StuffIt allows you to pick individual files from the archive and temporarily unpack and preview it without doing that to the whole library. Transferring archives between various packing formats is also no problem and of course doing that between PC and MAC platforms. For me StuffIt is an everyday tool I won't miss!
