Xtreme Download Manager is a non-installation tool (written in Java SE 6), allowing you to increase the download speed by up to 500 percent, as well as a number of other useful features. If you use Xtreme Download Manager, you can resume or restart downloading a file whose download process has been completely interrupted or stopped, for example due to a power failure or due to expiration of a session. The program supports HTTP, HTTPS and FTP protocols with authentication, proxy servers, cookies and redirection option.

Xtreme Download Manager integrates with every web browser (Firefox, Chrome, Internet Explorer, Opera, Safari and others). An important feature of the program is the option of downloading files saved in FLV format from popular websites such as YouTube, MySpaceTV or Google Video. Xtreme Download Manager can be configured so that after the download process, the tool checks for viruses and closes the operating system when the download is complete.
