iPhoto, Exterminate Duplicated Photos

Upon importing our most memorable photos to iPhoto, duplication of original photos can't be avoided, sometimes even take up most of our precious storage space. I believe we won't let duplicated stack of photos fill up our free space.

In the case that you want to free your storage, you can delete your original photos. But beforehand, let's check whether those photos are already inside your iPhoto Library.

There is an usual place where you can find those mentioned photos…

Inside iPhoto Library

By default, iPhoto Library will be created and saved to Pictures folder under your username. Make sure you find it and then follow these steps to see all imported photos.

1. Control-click on your iPhoto Library
2. Choose Show Package Contents from appearing contextual menu
3. You will see several folders inside
   • Originals - Store Imported Photos
   • Modified - Store Edited/Modified Photos
   • Data - Store Scaled Down Thumbnails
   For more information, you can find out more inside The iPhoto Library Folder Help.
4. After you've seen those photos, you should have rest assured to delete your original photos and remove duplicates

By removing duplicated photos, I've managed to get extra 5GB available space for my Mac.

Other Unknown Places

Perhaps you've never created your iPhoto Library inside Pictures folder and you can't remember where you've built it. You can open your iPhoto, control-click on one of the thumbnails and choose Show Original File.

After you've finished the cleaning, don't forget to empty your trash~

Just to re-emphasize, you can delete photos from outside iPhoto Library from where they're imported from (let's say from your Photos folder); Any photos inside iPhoto Library aren't to be deleted.
