title: Get file download link in codeigniter
body: <p>I'm trying to download some files in my web application. Apparently I placed the files to be downloaded in a folder inside the controllers folder, somewhat similar to this:</p>
  
  <pre><code>controllers/upload/project_name/bc68gdas9jfeh9yfj/file.dat
  </code></pre>
  
  <p>Apparently I want to download file.dat but I don't know what to put in my  tag for my links. What do I put in my href so I could download the said file?</p>
