Question

Answer 1

You may want to use plupload form element instead. Install Plupload integration module and then use something like:

$form['my_element'] = array(
  '#type' => 'plupload',
  '#title' => t('Upload files'),
  '#description' => t('This multi-upload widget uses Plupload library.'),
  '#upload_validators' => array(
    'file_validate_extensions' => array('jpg jpeg gif png txt doc xls pdf ppt pps odt  ods odp'),
    'my_custom_file_validator' => array('some validation criteria'),
  ),
  '#plupload_settings' => array(
    'runtimes' => 'html5',
    'chunk_size' => '1mb',
  ),
);
