WinZip OnLine Store. We have all used the venerable WinZip at one time or another. We all get zipped file attachments, which contain more than one document or file. Zipping and unzipping file groupings is an efficient way to transmit files across the Internet. WinZip has a new version, 19, that costs $49.95; but, which can be purchased as an upgrade for $14.95. I confess that I don't use it as much as I should, but I have made a resolution not to make my correspondents download a group of files one at a time from now on. What are you using?
