Megatools is a collection of programs for accessing the Mega service from the commandline of your desktop or server. It allows you to copy individual files as well as entire directory trees to and from the cloud. You can also perform streaming downloads (for example, to preview videos and audio files) without needing to download the entire file. The tools are robust and optimized for fast operation, as fast as the Mega servers allow. Memory requirements and CPU utilization are kept at minimum. You can register an account using a "megareg" tool, with the benefit of having true control of your encryption keys.
