What to know before you begin
Compare Windows free-space readings before and after completed file operations. Results shown in a scan are candidates, not necessarily space already recovered. 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 can I verify how much storage Czkawka saved?
- Record free space in File Explorer before cleanup.
- Inspect group selections and estimate only the copies chosen.
- Apply actions in a small batch after backup.
- Refresh disk properties and compare available bytes.
Important limitation
How to verify the result
Verify a consistent free-space increase using the same drive measurement. 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.
