Need help oppening .anim file in a text editor (Visual Studio, Notepad++) (Unity 2017.4.15f1)

Good day people of the Commonwealth!
I need some help
I am following this tutorial:

I am stuck at 10:59
This guy somehow manages to edit the Unity .anim file with the Visual Studio
But when I try to do the same, the file looks encripted for me
Does any one knoe something about this?
And how to access the .anim file with lets say Notepad++

 

You probably have the wrong serialization mode.

Edit->Project Settings->Editor

Set "Asset Serialization" to "Force Text".

 

1.Open notepad
2.Now, try to drag the anim file into the notepad.

Worked for me this way!
