What is the difference between .tcr and .rgf?

Description: The TCR file format is associated with eBook files specifically used by Psion Series 3 devices. Psion Series 3, a range of personal digital assistants (PDAs) developed in the early 1990s, utilized these files to store and display electronic books (eBooks). TCR files are designed to be compact to suit the limited storage capacities of early PDAs. They contain the text of the eBook, and possibly basic formatting, optimized for the low-resolution screens of the Psion device.; 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.
