I've always used Aladdin's Stuffit Expander (free d/l at link) to decompress .zip's, .sit's, .rar's ... just about anything in any compressed format. it's understandable, though, if you wouldn't want to install a program just for one item... let me know and I'll see if I can e-mail you a zip (approx. 4.5Mb)
