Windows 2000 IE

Hello, My question is today I was downloading a ZIP file and for some reason IE asked me if I wanted to always download and open the files after they were downloaded. I want to know how I reset this so that it won’t do it as everything I go to download a *.zip or *.tar file it just says “Saving to Temp folder” then winzip pops up wanting to uncompress it which is really a pain in the butt. How do I reset this option so when I click on it, it asks me to download instead of auto downloading?
