Trouble opening a downloaded zip file?

Question

I have downloaded a group of exercise files from a training site. They are broken into three zip files with extensions .z01, .z02, and .z03. I have win rar and win zip but neither will open these files. I tried starting with the last one, that did not work. Any suggestions?
