What to know before you begin
Czkawka can group files by content-based checks rather than matching filenames alone. Use the duplicate-files mode and review full paths before selecting copies for removal. 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 does Czkawka find exact duplicate files?
- Add the folder or drives you want to inspect.
- Select the duplicate-file finder and the content-oriented comparison strategy if offered.
- Run the scan and sort groups by file size or count.
- Open representative files and mark only redundant copies.
Important limitation
How to verify the result
Verify retained files open and duplicate groups are explained by matching 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.
