The files being uploaded are being emailed to the submitter in response to their request for public records.    I would like to be able to determine the total size of the file(s) that are to be sent.   Our email server will only accept X amount to be sent.    I would like the process diagram to be able to decide if the reply should be emailed or it needs a different option.

I was looking at something like:

  var totalSize = 0;

  $("#q5 input").on('change', function() { 
  	$("#q5 input").each(function() {
    
    	for (var i = 0; i < this.files.length; i++) {
      		totalSize += this.files[i].size; 
    	}
      alert("Total Size: " + totalSize);
	});
  });

Which does add up the total file size but does not iterate over each file,  this.file.length is always 1.   And it does not trigger when a file is deleted.
