title: blueimp detect folder structure
body: <p>I'm using the Jquery File Upload of Blueimp.</p>
  
  <p>When I drag&amp;drop a folder structure like this:</p>
  
  <pre><code>/img/file1.jpg 
  /img/img2/file2.jpg
  </code></pre>
  
  <p>the plugin detects the files included in subfolders, but it keeps a "root" structure in the upload, so my upload it's like:</p>
  
  <pre><code>/img/file1.jpg
  /img/file2.jpg
  </code></pre>
  
  <p>is there any way to mantain the folder structure of the drag&amp;drop folder?</p>
  
  <p>thanks for the help</p>
