The folders are cryptically named and are only helpful if the vendor has pointed you where to find the file you need. It is perilous (risk of permanently making it not work again) for the head unit if you flash the wrong firmware.
Don’t randomly flash random firmware. Even if you think it may be correct, it probably is not. Best to seek advice from the vendor or the experts at the https://www.xda-developers.com/ forum for Android-based car radios before any flash. Be sure you know why you need to flash. Some updates bring improvements but at the cost of disabling other features. Be sure you know what you will lose, as you can’t roll back a flash.
