JDownloader

JDownloader is a powerful Open Source, cross-platform download helper. It simplifies downloading files from hundreds of One-Click-Hosters like RapidShare and Megaupload, for both premium and non-premium users.

Main features:

• Downloading in multiple parallel streams
• Automatic CAPTCHA recognition
• Automatic file extraction
• Resolves “protected” links from sites like Protector.to

Because JDownloader is written in Java, you need a functional Java Runtime Environment (JRE) before you can use it. You should prefer Oracle Java, OpenJDK sometimes has problems running JDownloader correctly.

1. Add the following PPA repository:
   • ppa:jd-team/jdownloader
2. Simply install the following package(s) afterwards:
   • jdownloader
3. Run a plugin update. You need up2date plugins to make sure everything works as expected because the supported hosters are changing their APIs and forms from time to time. And the corresponding JDownloader plugins have to follow these changes.

After installation, you can start the program by clicking “Applications→Internet→JDownloader”. Or open a terminal and start it via jdownloader.

Beause JDownloader is written in Java, you need a functional Java Runtime Environment (JRE). If you don't have a JRE installed, JDownloader tries to install the JRE during its setup.¹⁾

1. Simply download the Windows installer and execute it with administrator privileges.
2. Run a plugin update. You need up2date plugins to make sure everything works as expected because the supported hosters are changing their APIs and forms from time to time. And the corresponding JDownloader plugins have to follow these changes.

You should disable the clipboard monitoring feature if you are handling private data and URLs. JDownloader may copy the clipboard's content/URLs into a logfile if monitoring is active. Just use the icon the GUI provides to enable or disable it:

1. To change the download directory, go to “Settings” tab, “Download & Connections→Download directory”
2. To change used language, go to “Settings” tab, “User Interface→Language”

By default, JDownloader tries to merge downloaded multi-part archives and extracts archives. It keeps the original archive files to be on the safe side.

• If you want disable the automatic merging and/or extraction, disable the addons which are responsible for this:
  • “Addons→HJSplit”, uncheck “Enabled”
  • “Addons→JD Unrar”, uncheck “Enabled”
• For automatic deletion of the original files after successful merging/extraction go to “Settings” tab:
  • “Plugins & Add-ons→Extensions→HJSplit→Delete archive after merging”
  • “Plugins & Add-ons→Extensions→JD Unrar→Delete archives after successful extraction”

JDownloader's default style is very slow if running on GNOME. If you want to reduce JDownloaders CPU usage, go to “Settings” tab, “User Interface→Style” and choose “Light(GTK)”. Restart JDownloader afterwards, it should run much smoother now.
