Most people use their Web browsers for downloading files, but a browser isn't always the best tool for the job. If you are trying to download a YouTube video, or a very large file that may take hours, an external download manager might do a better job than your browser. JDownloader is one such download manager, and since it is Java-based, it works across Windows, Mac and Linux.

Once installed, JDownloader added a shortcut to the Windows 7 list of applications on the "outside" of the Start menu. Clicking the shortcut, however, simply ran an update utility--not JDownloader. I tried this twice, and the update utility ran both times, launching JDownloader only once it finished slowly checking for updates. To launch JDownloader directly, I had to open All Programs and track down the JDownloader shortcut there. Once I clicked that, JDownload ran correctly.

This concludes the bad part of the user experience. Once you're in JDownloader, you have one of the world's most sophisticated download managers at your disposal. JDownloader can be used as any general-purpose download manager, and it also supports dozens of file hosts such as RapidShare and others. It can monitor the clipboard and parse any URL you copy into it to see if it contains files that could be downloaded. If you feed it with a YouTube link, it lets you download the video in any resolution offered on the page.

JDownloader is built from the ground up to deal with file hosts that do not let you pause downloads; that's why its "pause" functionality doesn't actually pause the download altogether, but slows it to a crawl, letting you use your bandwidth as needed. It also has a built-in extension system, and extensions can be installed from within JDownloader itself (much like jEdit, a Java-based text editor). There are extensions for unzipping downloads automatically, scheduling downloads to begin at certain times, and more.

While I love JDownloader and I appreciate the fact that developer AppWork must somehow make money, I really can't get behind the installer changing the homepage, default new tab page, and default search provider. Such tactics are traditionally reserved for the lowest of the low, which JDownloader is certainly not. I'm not saying you shouldn't install it: It is one of the best download managers available today, and at a price that can't be beat. But you should make sure you get the PCWorld installer, not the one from the JDownloader website. If you do try it and like it, consider donating to the developer…and letting them know how much you appreciate the installer that installs JDownloader alone.
