How display file path at bottom in "All My Files" on Sierra 10.12.3?

How can I enable this on Sierra (10.12.3)?

The one you reference in the screenshot can be enabled in either of the following two ways:

1. Ensure the Finder is active
2. Go to the View menu
3. Select the Show Path Bar option

Using the keyboard

3. Select the Customise Toolbar... option
4. Drag the Path icon to your toolbar
5. Click on Done

Note: The icon looks like:

You can display the file path at any time without changing any preferences. Just command-click the proxy icon in the title bar of the window.

The file path appears just like it would when using the file path icon. The great thing is that this doesn't just work in the Finder -- it will work in most applications in which you have a file open in a window.
