title: Fine-uploader using addFiles to upload a file server side
body: <p>In the API documentation it says that addFiles can be called with "An array of Files", I cannot work out how to do this as every time I call it I get this error.</p>
  
  <p>[Fine Uploader 5.11.2] /tmp/file.png is not a valid file container!  Ignoring!</p>
  
  <p>Also to note I did try using an array to pass the files, no luck.
  My code:</p>
  
  <pre><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"&gt;&lt;/script&gt;
  &lt;script src="client/fine-uploader.min.js" type="text/javascript"&gt;&lt;/script&gt;
  &lt;script&gt;
  var uploader = new qq.FineUploaderBasic({
      debug: true,
      request: {
          endpoint: 'server/endpoint.php'
      },
      success: {
          onComplete: "server/endpoint.php?done"
      },
      });
  
  function readFile(filePath){
  uploader.addFiles(filePath);
  }
  
  var files = ["/tmp/file.png"];
  
  &lt;/script&gt;
  &lt;script&gt;readFile(files)&lt;/script&gt;
  </code></pre>
