title: How to download or save files locally in Phoenix
body: <p>I figured a way to upload attachments locally using <strong>arc</strong> and <strong>arc_ecto</strong>. I however want to find a way where users of my application can download or save these uploaded files by just clicking on a download button on the browser. The downloaded files will be in a separate folder. </p>
  
  <p>I have gone through many sources but I seem not to still get it.</p>
  
  <p>Please how do I do this?</p>
