What to know before you begin
For routine cleanup, exclude Windows system directories and application program folders. Identical files can be intentionally present for servicing, recovery or software dependencies. 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: Should I scan the Windows folder for duplicate files?
- Remove C:\\Windows and Program Files from normal user cleanup scans.
- Add personal folders such as Downloads or Pictures instead.
- Use the exclude directory feature to block protected paths.
- Review exclusion lists before every large multi-drive scan.
Important limitation
How to verify the result
Confirm the scan scope contains only user-managed content. 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.
