Purpose of thumb_file/photo in iPhoto?
What is the purpose of thumb_ in iPhoto?
The reason I ask is because I recently downloaded some photo and video files from an external HD that contained my old iPhoto library . When the photo/video files were imported to my new iMac's iPhoto, the Jpeg_plusthumb_ pictures were both added to new iPhoto Events/Pictures.
Can I safely delete the thumb_ picture from iPhoto?
Thanks for advice.
