RB
Rocket eBook
Was developed for the first mass-produced e-book reader – Rocket eBook. The format is written in Ruby. RB files are containers holding the entire content for a Rocket eBook device. It has DRM protection capability which is not used in the books published at present due to the format’s lack of popularity.
DDS
Microsoft DirectDraw Surface
This is the format that is used in the OpenGL and Microsoft DirectX development environment. It is used to store bitmap images of user interface environments and textures. It allows you to store information in compressed and uncompressed forms. It is used for texturing game models and storing entire textural arrays to create games and 3D-software applications. DDS is used to develop the latest-generation video game consoles. It makes it possible to compress texture blocks 'on the fly', which increases performance when you run the application.
