Can HTML 5 drag-and-drop handle folders?

Question

I'm impressed by Gmail's ability to let you drag files into emails for attachments, but when I try to drag a folder onto it, it says the file has 0 bytes. Is this a Gmail limitation, or is this something that's fundamentally not doable with the current HTML 5 spec?

Answer 1

Now directory upload available on chrome

you can select directory using input type

<input type='file' webkitdirectory >

and you can drag drop a folder

<div id="dropzone"></div>

var dropzone = document.getElementById('dropzone');
dropzone.ondrop = function(e) {
  var length = e.dataTransfer.items.length;
  for (var i = 0; i < length; i++) {
    var entry = e.dataTransfer.items[i].webkitGetAsEntry();
    if (entry.isFile) {
      ... // do whatever you want
    } else if (entry.isDirectory) {
      ... // do whatever you want
    }
  }
};
