This question already has an answer here:
I have GNOME Shell 3.16.4 installed on my Ubuntu 15.10 machine. However I get the old boring Unity like file manager. Here's a picture of my file Manager. See the top bar is like Ubuntu and button are on the left.
However, I want this my top bar completely like one below. Where you get to type the path. Also, you get the close, maximize and minimize button on the right and only back-forward buttons on the left.
