Why does iPhoto duplicate photos when importing?

iPhoto duplicate photos when importing to protect your digital photo collection. Go to File > Preferences > Advanced, and you can find the Importing option Copy items to the iPhoto Library. It is also available in Photos. The option is enabled by default.

If this option is enabled, when you drag photos from somewhere on your Mac, say, the desktop, into iPhoto, iPhoto will copy the photos into the library. In other words, it duplicates them. Now you actually have two copies of each imported photo.

To prevent iPhoto from duplicating photos, you can unselect the checkbox before Copy items to the iPhoto Library. However, it is NOT recommended. If you set iPhoto not to store a copy of the photo it imports and you accidentally delete the original copy, when you try to view the photo in iPhoto, a message will pop up telling you that it can’t find the file.
