What to know before you begin
Choose a trusted reference copy based on path, file quality, metadata and backup status. Automatic selection should never be used without checking its criteria. 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: How do I choose which duplicate file to keep?
- Sort each group by directory and inspect the location of every copy.
- Prefer a known backup or source folder as the reference path.
- Preview at least one representative file in each group.
- Select only the extra copies after verifying the reference copy.
Important limitation
How to verify the result
Verify the retained path exists and the file opens after cleanup. 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.
