That's amazing Patricia! :) You and I seem to be the "oddballs" here :) If you read my last post you'll note that Stuffit is how I eventually got them all to open! :) I had the same experience when trying to open with the Windows XP extractor......there appeared to be content inside each zip, but I could not get the method I normally use to extract it. Maybe you should try downloading Winzip for Mac (assuming there is such a thing) and see if that works! :)
