title: When user clicks on link I want to unzip file and then open it
body: <p>I would be grateful for help concerning this issue:</p>
  
  <p>User clicks on a link:
  the link itself has the parameter that tells which file needs to be unzipped to /unzip folder. After a file is unzipped, I would like to open the file. </p>
  
  <p>How can I do this? I have the unzip part coded already.</p>
