What to know before you begin
Czkawka concentrates on detecting duplicate or unnecessary files, while WinDirStat is known for visualizing disk-space usage. They solve related but different tasks. 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 the difference between Czkawka and WinDirStat?
- Use a disk visualizer to locate large directories.
- Use Czkawka to inspect exact duplicate groups within those directories.
- Check scan settings before removing any candidate.
- Measure free space after approved actions.
Important limitation
How to verify the result
Verify both tools point to the same drive and folder scope. 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.
