I am a blogger and I had thousands of duplicate images on my PC. I tried so many software but they didn't have the feature of Bulk images and were too slow. A friend of mine recommended Duplicate Photos Fixer Pro to me and I am quite happy with the results. I will recommend it to everyone who is dealing with such an issue.
