What to know before you begin
The mode, scan scope, excluded paths, size filters, permissions or cache can hide candidates. Use two known identical test files to isolate the reason. 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 known duplicate files missing from a scan?
- Confirm both files are inside included directories.
- Check exclusion patterns and minimum file-size filters.
- Use the exact-duplicate mode rather than visually similar images.
- Retry a small test directory after reviewing cache behavior.
Important limitation
How to verify the result
Verify a test pair is grouped before widening the scan. 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.
