A file with the BR5 file extension is most likely a scene file used and created with the Bryce modeling software, which can be used to create 3D landscapes.
Typically the file contains 3D environments full of things like lighting effects, lifelike water, etc., but it can also contain other 3D models and objects, such as animals and people.
Other BR5 files may instead be music files created when a BMW car backed up a music collection via USB. If they don't have the BR5 extension, they may be similar, with a .BR3 or .BR4 extension.
