IE: input type="file" multiple

Question

How come IE 9 does not support input type="file" multiple like other browsers do?

<form action="#" method="post" enctype="multipart/form-data">
  <input type="file" multiple name="uploads[]" />
  <input type="submit"/>
</form>

How can I make it work on IE?

Answer 1

Uploading multiple files is a specific part of HTML5 that none of the Internet Explorers support.
