I know that there are a fair few AJAX file upload components floating around out there which allow a user to select multiple files to upload to the server and to upload them at once by pressing a button or clicking a link. What I am wanting to do is set it up so that I can drag one of my files from my documents folder into a specified div on the page and it adds the file for upload and begins uploading it immediately using the async upload service of AJAX. Does anyone know how I would go about doing this.
