It’s not finding my duplicate photos!

Duplicate Photo Cleaner uses a true SHA-1 checksum file compare to ACCURATELY find legitimate duplicates. This basically means that it finds all TRUE duplicate files by looking at the actual HASH value. Renaming a file with a different name doesn’t change this. Similar photos are not exact duplicates and do not have the same hash value.

If the photo contents are altered, then it is no longer a legitimate duplicate and Duplicate Photo Cleaner will not flag it as a duplicate.

If it is not detecting your images as duplicates, then they are not TRUE duplicates. They were altered. Duplicate Photo Cleaner only finds all legitimate duplicate files.

You can check your SHA-1 and MD5 hash checksums to see if they are true duplicates by following the guide in this article:
