File path in preview app. finding files

It is not the role of Preview, or Safari to track down file locations on macOS. although you can see a file's current folder location by clicking on its title bar name in Preview. It is the role of a properly configured Finder.

Mine is setup this way via Finder Preferences:

1. General
   1. Check all Show these items on the desktop
   2. New Finder windows show: [ 🏠 yourname ]
2. Sidebar
   1. Check 🏠 yourname
   2. Check any other that you want to see that are not defaulted, including iCloud Drive if you use it
3. Advanced
   1. When performing a search: [ Search the Current Folder ]

I also suggest that you enable the following in the Finder View menu when you have a Finder window present

1. Show Path Bar
2. Show Status Bar

There are three ways you can search from the Finder on your Mac without using a third-party tool like EasyFind.

1. Spotlight 🔍 from the menu bar
   1. Select a result from the search and press ⌘R to open a Finder window with the item selected
   2. Press the ⌘ key to view the full path to the selected file
2. Spotlight from the search field in a regular Finder window
3. Using ⌘F shortcut to open a Finder Find window, where you combine search criteria in the Find process

Items 1 and 2 immediately above, depend on enabling Spotlight to index certain search result categories listed in System Preferences : Spotlight : Search Results. You enable Spotlight indexing by dragging and dropping the startup drive (e.g. Macintosh HD) icon onto the open Spotlight Preferences : Privacy tab, then removing it from that panel. Then you can use Spotlight reserved words to Narrow your search results on Mac.
