how to delete original file in photos?

Anyway, the question: is there a way to automatically delete both? In adobe lightroom, there are options to "delete from disk" and "remove".

In Photos you have to remove the referenced files manually. Use the command "File > Show referenced file in Finder" before you delete the photo from the Photos library.

right - Photos does not delete anything not in its database so the originals in referenced phots are not touched - when you use referenced photos you are accepting the responsibility for managing teh originals photos - and this is one (of many) reasons that referenced photos are not recommended - :Disadvantages of a Referenced Library in Photos

Photos is not a photo viewer but is a total photo management solution - you probably are just using the wrong program for what you want

you are welcome - good luck

It is not - Photos is a consumer program and both of the programs you used to user are professional programs - they do not have the same capabilities

If you have and understand LR I'd suggest you keep using it - Photos capability pale compared to LR as expected for a free consumer program compared to an expensive professional program
