A zip file is a compressed collection of one or more files. It is not a file type. You have to extract the files from the zip folder to see what is in there. Knowing what extensions the unzipped files have would be usefull. You can use winzip or winrar. Put the zip folders in a new folder before unzipping as it may contain one file or 100. Keeps everything in one place. Free ones http://www.snapfiles.com/freeware/downloader/fwzip.html
