I am relatively new to Photos. I have a hard drive that has nothing but images and photos from many different work and family sources. I imported all of them (over 40k) into Photos thinking that I would be able to use it as an actual management system. However, I found that it's not finding duplicates and I can not delete any images from the hard drive within the Photos application. Is there a way to delete an image inside the Photos application and have it removed from the hard drive as well? I haven't been able to find a way to do this. Any help would be much appreciated! Thanks!
