Deleting Photos From "Photos" App Does Not Delete Them From Local Drive I have some photos and I want to remove some of them by first previewing and then removing, like I always do on Windows.

Because "Preview" does not let me look multiple photos and "Quick Look" has no delete function, I imported the photos to "Photos" app by dragging the folder into the app and started to removing photos.

Then I also go to recently deleted tab in "Photos" and deleted photos permanently.

But it does not remove them from local drive. They are still on my drive, I can see on Finder.

How do you remove photos in MacOs? I could not find an easy way to remove photos "on fly". If possible, I don't want to use 3rd party apps.
Photos app stores the pictures in a database. There will be an original copy of the image, a copy of the image if you edit it in any way as well as proxy / thumbnail photos so that various functions are fast.

These files are all stored and managed via the application and default are stored as a directory or folder on the filesystem that is shown as one icon. Look in your Pictures folder in your home folder. (Shift Command H in Finder to short cut to your specific home folder).

Any photos stored outside that location can be deleted using finder, search tools, etc.. and using Photos won't help manage them. Any photos stored inside the photo library should not be deleted, so they are generally hidden from search to prevent people from breaking the library database.

Most people don't ever have more than one Photos library, but here are documentation for those that prefer to know how things are stored.
