How Do I Delete Duplicates Pics Without Deleting Pics From Albums?

I have a large Photos library of over 2TB. I used PhotoSweeper Lite to identify over 145GB of duplicate pics that have accumulated over the years.

I have organized my pics into various albums that I have created, and I of course want to keep those pics in those albums. So I need to figure out how to delete the duplicates that are NOT in an album and keep the version of the picture that is in an album.

I understand that PhotoSweeper Lite can create a separate folder in Photos of pics that I can choose to delete (in other words, it doesn't automatically delete duplicates).

Is there a way to identify the pictures that I have placed in albums that will allow me to easily determine which pics to keep and which to delete?

Thanks
