FreeRapid Downloader is a file downloader written in Java. It downloads files off file sharing services like Megaupload and Rapidshare, hence the name. It runs on any platform that is supported by the Java framework.
The application is extremely simple. It can't grab download URLs (links) from a specific website, so you have to add those by hand. Still, you can add more than one at a time, which is nice and saves time. The application is continuously adding new plug-ins which allow it to work with other services and offer new features. One of those plug-ins is the captcha faker, which automatically inputs the capture text that you are asked to input before downloading a file.
There also is a clipboard monitor that detects when a link that the application can download is added to the clipboard and automatically inputs it into the new download dialog. Sadly, FreeRapid is still missing a scheduler and some key features for this type of application. However, using this application still beats downloading files off file sharing services manually.
FreeRapid Downloader is also a portable application, which you can carry on your USB drives.
