Ajax Uploader is an easy to use, hi-performance ASP.NET File Upload Control which
allows you to upload multiple files to web server without refreshing the page.

Client side validation of the file size/type before uploading
Client side validation of file size/types prior to uploading the files to a server to increase usability and reduce consumption of network and server resources.
Hi-Performance with optimized memory usage
By streaming uploads directly to an output stream, rather than loading them into memory, This file upload control achieves a level of scalability and performance impossible to reach with ASP.NET's built-in functionality.
