title: How do I configure IE7 to download filetype instead of opening in browser
body: <p>I have written a watir script that downloads files. One of the files it downloads has a .dcf extension. Months ago, on my machine, I changed a setting somewhere so that .dcf files prompt for download ("Do you want to open or save this file?") instead of opening in the browser. This is the behavior that I desire.  I am using XP Pro/IE7.</p>
  
  <p>I'm now setting up a dedicated test machine, but cannot seem to find the configuration option that I did on my machine - which was so easy to find that I didn't make note of it.  All of the solutions that I am finding now are either about changing the download itself or modifying the registry. I am looking for something from the client perspective at the browser/IE level.</p>
