what is the easiest way to delete duplicate photos

Wendy152,

Which app do you use to organize your photos? Without knowing that basic info we have to guess. When asking a question on a forum, please be complete. Something like, "I am using Yosemite 10.10.5 and use Photos for Mac to organize my photographs. I noticed I have many duplicates, how can I get rid of the duplicates files?"

What 2 programs & their versions did you use to remove the duplicates?

I Am using the photo app from Apple that replaced iPhoto. My running system is Yosemite 10.10.5. All up to date.

Photos does not support the removal of duplicates.

And there are not yet many applications that can detect or remove duplicates in a Photos library.

These apps are compatible with Photos:

• Power photos: Fat Cat Software
• Duplicate Annihilator: Brattoo Propaganda Software - Products
• PhotoSweeper: http://overmacs.com/photosweeper.html

What kinds of duplicates do you have in your Photos library? Exact duplicate image files? Edited versions of the same photos? The same photos at different resolutions or in different image formats or resolutions?

For exact duplicates should Power Photos or Duplicate Annihilator suffice. For edited versions or scaled down versions would Photo Sweeper be the best option.

These applications will identify and help remove duplicate photos from a Photos Library:

• Duplicate Annihilator for Photos - $7.95
• PhotoSweeper - $9.99 - Demo version available.
• PowerPhotos - $19.95
• Duplicate Cleaner for iPhoto - Free

PowerPhotos is the iPhoto Library Manager version for Photos and is very powerful. Although more expensive I would recommend it as it has more capabilities than the others and will have added capability in the future.
