Czkawka Similar Image False Positives

What to know before you begin

Visual similarity is an estimate, not exact duplication. A permissive threshold can group photos that merely share colors, composition or background. The project offers several scanning modes and the current version may place controls differently in Krokiet versus the older GTK GUI. Follow the meaning of the option you see, not just a screenshot from a different release.

For Windows, verify that your chosen folder is accessible and that the correct graphical frontend is running. The recommended approach starts with a small test set, especially when an action could rename, move, delete or link files.

Step-by-step: Why are unrelated images grouped as similar?

1. Create a sample folder with clearly different images.
2. Reduce the accepted difference threshold.
3. Repeat the comparison and inspect before/after groups.
4. Separate exact-duplicate cleanup from similarity reviews.

How to verify the result

Verify the new result list has fewer unrelated groups. A scan's estimated savings or the presence of a matching group does not by itself establish which copy should be discarded.

If the procedure does not match your screen, inspect the project's own FAQ and troubleshooting notes and identify the exact release and frontend first.
