This code block might help:

document.getElementById('files').addEventListener('change', handleFileSelect, false);
var files; 
/* Helper Functions*/
function handleFileSelect(evt) {
files = evt.target.files;
    // Loop through the FileList and render image files as thumbnails.
    for (var i = 0, f; f = files; i++) {
      // Only process image files.
      if (!f.type.match('image.*')) {
        continue;
      }
      var reader = new FileReader();
      // Closure to capture the file information.
      reader.onload = (function(theFile) {
        return function(e) {
          // Render thumbnail.
        createSpanAndInsert(['<img class="thumb" src="', e.target.result,
        '" title="', escape(theFile.name), '"/>'].join(''), 'list')
        };
      })(f);
      // Read in the image file as a data URL.
      reader.readAsDataURL(f);
    }
  }

note that this example lets users choose image files.

Hi there awaisu!

Have you checked out our guide to exporting files from the host app? It's pretty thorough.

Let me know if that helps or not, I've got a few people I can ask.
