I noticed that iPhoto created hundreds of copies of my photos while looking for faces and they are stored in the iPhoto library. I don't like the faces feature because it doesn't really work and I would like to delete these extra files from the library to regain lost space. My question is, will iPhoto just keep trying to recreate face files every time I open the app or do I have to click on the faces tab to make it start trying to generate face image files? And is it a problem to just delete these face files? Does iPhoto make additional copies of these face files in other folders as well or would it all be contained inside the iPhoto library folder that is in my pictures folder? Thanks a lot for any advice.
