My workflow involves (1) taking photos and importing them to a folder (2) Selecting the files I want to keep and (3) deleting everything I don’t want. This can be done in PL, but it’s not simple or fast.
Another app I use allows me to mark the “keep” files, select all the “keep” files, then invert the selection and delete them. What’s left are the “keep” files. Simple and fast.
