Hard Drive Management.
Sorry about dejavu. I accidentally set original as solved!
I'm running Monterey 12.3.1.
I moved the Photos Library to an external HD and that is working fine.
I deleted the Library from my Hard Drive and it is no longer shown in Finder.
But when I go into About This Mac, Storage, then manage it still shows the Library Icon and 79.42 GB.
What has gone wrong and how do I fix it please?

Someone suggested Inventory X and I'm now working my way through its results. Still have original problem but solved one I didn't know I had!
