JDownloader is open source project made to download files from file hosts as easy as it can be. It supports premium accounts. The whole software is made in java, so it is supported by all operating systems. It contains very useful extensions (such as unrar – everything you download is automatically extracted without any interaction of user).

The reason why I mention JDownloader is support of .dlc files (containers) which contain encrypted links. Those link can not be tracked and reported. That means they stay alive as long as they can. Such a links will be used in siterips in the future because it takes a lot of time to upload everything and nobody wants that deleted in a couple of days.
