Which Folder Are Files In?

In Finder's View menu, select Show Path Bar. Then when you click on a file, its path, including enclosing folder will appear at the bottom of the Finder window.

Another approach is View menu : Customize Toolbar… and then drag/drop the Path tool onto an open Finder window's toolbar. Then, when you want to see the enclosing folder of a selected file, click that Path tool, and the top menu item is the current folder.

If you were performing a Spotlight search for a filename, you would press the ⌘-key to see its path and enclosing folder, or you could press Return and a Finder window would open with that file selected.

If you're not used to the Mac GUI, then in the Finder go to the View Menu → Show Path Bar which should then show you a breadcrumb trail of which folder you are in and where it is within your Mac at the bottom of any Finder window. Alternatively, click on the name of the folder (top and middle of folder window) you are in whilst holding down the Command key and a drop down menu will appear showing the path

Snap. Although I like your Customize Toolbar option. I've not tried that before. I reckon you learn something new every week

You are welcome.
