title: How do you get the value of a file when the HTML5 Files API (FileList to be specific) is not available?
body: <p>Google Apps Script HTML Service (<a href="https://developers.google.com/caja/" rel="nofollow">Caja</a>) is not compatible with HTML5 APIs, including the Files API. Therefore, I'm incapable of calling the Files property from the input object.</p>
  
  <p>An approach that circumvents this issue and allows for me to handle each individual uploaded file would be greatly appreciated as all the solutions I've found across the internet involve HTML5.</p>
