My friend told me a great files download manager called JDownloader last month. I did not have the chance to try it until now. JDownloader simplifies downloading files from One-Click-Hosters like Rapidshare.com or Megaupload.com. It offers downloading in multiple parallel streams, captcha recognition, automatically file extraction. Therefore, you just need paste the download links into JDownloader and let it runs the show. Most important part ~ it is FREE.
