JDownloader is an open source, platform independent, written completely in Java, download manager, targeted mostly at One-Click-Hosters Rapidshare.com or Megaupload.com. It does not only work for users with a premium accounts but also for users who don’t pay by automating the captcha verification process through custom character recognition. It offers downloading in multiple parallel streams, captcha recognition, automatic file extraction and much more. As open source suggests, JDownloader is absolutely free of charge. Additionally, many “link encryption” sites are supported – so you just paste the “encrypted” links and JD does the rest. JDownloader can import CCF, RSDF and the new DLC files.
Therefore, if you download a lot of files from free file hosting sites, but you are tired of entering Captchas and waiting for your downloads to begin, jDownloader can help. jDownloader can handle your downloads from several file hosts, allowing you to queue up a bunch of files which it will then proceed to download in the background, either through your premium account or as a free user, by reading Captchas. Basically, no matter if you are paying or not you don’t have to be near your computer when downloading, but you can get it to download everything by the time you get back. It works perfectly with downloads from Rapidshare, Megaupload, Depositfiles, Netload.in, Filefactory, Uploaded.to, ZShare, etc (Full List)

Although Jdownloader is very useful it does have a few quirks and requires some of your attention.
First, jDownloader requires Java to run and you don’t install it like a regular Windows application. Rather, you download and extract the contents of a ZIP file and then click the jDownloader.jar file to start the program. (For frequent Java users this should be a piece of cake, otherwise it requires some effort to get it done)
Second, jDownloader’s file menus are all by default in German. You can change the language to English, but you’ll still might find a few German words scattered around.
In case you don’t speak German, here’s how to change the deafault language:
1. Click the Extra button
2. Select Konfiguration
3. Select the Benutzeroberfläche tab
4. Under Sprache, select English
5. Hit the Speichern und neu starten button to save and restart in English
Now you’re almost ready to go. But before you can download any files you’ll have to accept the terms of service for each site you want to download files from.
1. Click the Extra button
2. Select Configuration
3. Select the Hosts tab
4. Check the boxes next to any file hosting service you expect to use.
Now you’re ready to start downloading. Just click the Add Links button and add links to any files you want to download, then click the Start button to begin downloading.
