File Type 1CATIA Graphical Representation File

CAD file created by CATIA, a CAD application used for product design; saves the visualization of a design (.CATPART or .CATPRODUCT), but only stores the geometrical information required to view the model instead of all the CAD data.
CGR files are used for sending design drafts for review. They can also be inserted into Adobe .PDF documents using the Pro Extended version of Adobe Acrobat.
File Type 2Quest3D Channel Group File
This file is saved in a binary format, which requires a specific program to read its contents.
File created by Quest3D, an engine used to create 3D programs; contains a group of "channels," or properties for the flow and display of objects, models, surfaces, textures, properties, and animations; used to store product visualizations, games, tutorials, animations, user interfaces, and immersive environments.
CGR files are always stored with complementing .IGR files, which contain the location of channels within the Quest3D Channel Graph layout pane. If the IGR files are missing, the channels will use a default layout and may be difficult to view.
CGR files are used in games such as Audiosurf, Leo, and The Endless Forest.
