If you download a lot of files from free file hosting sites like RapidShare and MegaUpload, but are tired of entering Captchas and waiting for your downloads to begin, jDownloader can help. jDownloader is a download manager that works with both sites, plus a few others. It lets you queue up a bunch of files which it will then proceed to download in the background. It can even read Captchas, which means you don't have to be near your computer when the downloads start.

The program does have a few quirks.
