With RadAsyncUpload you can quickly allow users to upload multiple files at a time – all it takes is setting the MultipleFileSelection="Automatic” property.

Please note that this functionality is possible thanks to the HTML5 File API in modern browsers and the Silverlight/Flash plugin in older browsers.

You can select several files at once from the file selection dialog.
