What does the.Unity file contain in addition to the scene info(name,rootgameobject and so on) and what the type of *.unity if  it makes sense to say that. 

The documentation actually covers this:  https://docs.unity3d.com/Manual/FormatDescription.html

https://docs.unity3d.com/Manual/YAMLSceneExample.html

https://docs.unity3d.com/Manual/ClassIDReference.html

Projects used to default to binary files, but I think text is the default now.  If your files are binary, you can switch them to text:  https://docs.unity3d.com/Manual/class-EditorManager.html  See: "Asset Serialization Mode".
