FinderPath is exactly what its name implies: a program that gives you access to Finder file paths. This application is very simple to install and handle, immediately displays the information you require, and doesn't slow down the performance of your Mac while running in the background.
The program doesn't come with an actual interface. Instead, it gives you access to a Preferences panel that comes with all of the available settings and, of course, the address bar from the Finder application. Before using this utility on your Mac you need to go to System Preferences -> Security & Privacy -> Privacy and enable the Accessibility option for the FinderPath. Afterwards, you can use the program whenever you need.
All you need to do in order to reveal the address bar in your Finder window is to type the default Command + G keys. You can always change this hotkey by going to the Preferences panel of the utility. Another way to display the address bar is to left click Finder's title bar. You can use this application if you need to immediately copy file paths on your Mac.
The program works perfectly. However, there's a Mac default solution for getting access to the path of a file within your directories. You can right-click over the file in question, select the Get Info option, and find the file location next to the "Where" info category.
FinderPath is free and quick when Mac's Get Info option requires some effort and time to complete. Hence, in my opinion, it's worth giving FinderPath a try.
