As web apps evolve, you might have found it handy to let users drag and drop files from the desktop onto the browser to upload. Ajax Uploader 4.0 introduces a very convenient drag and drop feature. The new functionality allows the user to drag a file directly into drop zone without the use of file dialog.
Note. The drag and drop functionality requires the end-user's browser to support HTML5 technology. It means that it works in modern browsers only: IE10+, Safari 6+, Firefox 4+, Google Chrome, and Opera 12+.
