What to know before you begin
A reference directory identifies files that should be protected when finding duplicates elsewhere. It is helpful for scanning a staging folder against a trusted master library. 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: What is a reference folder in Czkawka?
- Choose a trusted folder containing originals.
- Configure it as the reference source where your frontend supports the option.
- Add the folder containing copies as a separate included directory.
- Check a sample result to confirm reference files are not selected for deletion.
Important limitation
How to verify the result
Verify that the master copy was never moved or marked for removal. 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.
