What is the difference between .flv and .rgf?

Description: An FLV file is a flash-compatible video file exported by the Flash Video Exporter plug-in (included with Adobe Animate) or other program with FLV file support. It consists of a short header, interleaved audio, video, and metadata packets. The file stores audio and video data in a similar format used by standard Flash (.SWF) files.; The LEGO Mindstorms EV3 Robot Graphics File (RGF) is a proprietary binary file format used by the LEGO Mindstorms EV3 software to store robot graphic models. It is a vector-based file format that stores information such as the robot's 3D geometry, color and other visual properties, as well as the model's connection points, used for connecting with other LEGO elements.
