What to know before you begin
Zero-byte files can be leftovers, but some are intentional markers or placeholders. The empty-files mode finds candidates rather than assigning them a safe-to-delete status. 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: Are zero-byte files safe to delete?
- Scan a user-controlled folder, not Windows or Program Files.
- Review file names and extensions in the results.
- Check whether applications use those paths as marker files.
- Move a disposable candidate to a backup location before deletion.
Important limitation
How to verify the result
Verify normal folder or application behavior after removing test files. 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.
