Delete photos from all photos except album(s)

[brosahay]

Summary

A way to delete(move) "All Photos" except one or more albums.

Context

I have a few folder(s) which I do not want to delete meanwhile I want to delete the rest of "All Photos".
Let's say I have a folder "Vacation", now I want to download "All Photos" meanwhile delete them while keeping the photos intact in "Vacation" album.

One way I was thinking of doing the same was downloading "All Photos" and download "Vacation" in seperate folders and then run fdupes to deduplicate "Vacation" from "All Photos". Now I need to be able to delete photos that are present in the local "All Photos" folder, but currently I do not see this possible.
