JQuery File Uploader is a JQuery plugin actually which is used to drag and drop files, together with Ajax upload and Progress Bar. Other plugins are much jumbled with profit margin and arrange other techniques to make it accessible for early browsers. So, the idea for this plugin is just to keep it as simply as it can be. It won’t just focus on recent browsers but also be responsible for a system to discern when the plugin is not supported.
I hope this plugin will be useful for you.
