When I navigate to my "Pictures" folder, there are 29 folders in here titled: iPhoto Library Recovered Photos_1 iPhoto Library Recovered Photos_2 iPhoto Library Recovered Photos_3 iPhoto Library Recovered Photos_4 iPhoto Library Recovered Photos_5 . . . They all appear to be empty. Are these used for anything or can I delete them? Every time I start iPhoto, I get a message saying: A photo has been found in the iPhoto library that was not imported Would you like to import it? It appears this is what is causing the folders, as one is created every time I open iPhoto. I choose "Yes" for this option, but it always pops up. Can I delete all these folders that are created due to this message and how can I prevent this message from appearing every time I open iPhoto? Thanks!!
