I have soooooooooo many duplicate photos on my computer, but I don't know what happens if I delete some of them. I did this to check what would happen. I open iPhoto, choose a picture and open it (to check if i can open it) I find all the dublicates of that photo in finder, and delete them. I try to open the same picture in iPhoto, but now it just shows a blown up exclamation point. I go the the trash can, put all the photos back Try to open the picture in iPhoto (expecting it to open) but it STILL shows the exclamation point! I find this to be very weird. The files i deleted are back and yet it still won't recognize it as being there. I have Aperture and I can open the picture there with no problems. PS: If anyone knows, where are the pictures in iPhoto and Aperture stored? I have up to 5 copies of the same photo in my computer, but don't know which ones to delete without creating any problems. Thanks in advance!
