Is there an easy way to look through a directory, preview file by file, and choose to keep or delete it? I'm mostly looking to do an initial pass of a folder of 10k images and I want to go through one by one and mark each for deletion or for keeping. Any easy way to do that on a mac or is there a photo organization program that will do this?
Open the directory then instead of opening the image, you can press space to open a preview of that image. Now you can navigate through the images using your arrow ( ←→ ) keys.
If you want to delete any one of them then just go back to finder and the same image will be selected that you were previewing.
