    Este es un ejemplo que me encontre en la web y funciona esta hecho con ajax adaptalo a tus necesidades...

    NOTA: este ejemplo esta limitado para archivos de tipo .txt .zip y .xml sin embargo le puedes cambiar este comportamiento un poco mas abajo aparece para modificar este comportamiento...
