The RSD format uses a combination of images, text, and sound, and the difficulty levels rise in line with the student and their progress.
An RSD file is a media file that is basically a Rosetta Stone proprietary binary container.
The RSD format contains the lesson data for the student to learn vocabulary and grammar functions without any translation.
