JDownloader

JDownloader is a download manager, written in Java, which allows the automatic downloading of files and split files from one-click hosting sites. JDownloader supports the use of premium accounts. Some parts, but not all, of JDownloader are open source.

In December 2009 the program's website was in the top 1000 sites by traffic from Spain. The German online magazine, Chip.de designated it "newcomer of the year" for 2009 after it ranked among top 50 downloads with over half a million downloads for the year.

From mid-2012 there were complaints that JDownloader's installer installed adware without the user's consent. The JDownloader installation contains AdWare according to several sources, including the developer's own forums. There were further complaints from mid-2014.

In June 2013 JDownloader's ability to download copyrighted and protected RTMPE streams was considered illegal by a German court. This feature was never provided in an official build, but was supported by a few nightly builds.
