Short answer: Can I scan OneDrive files with Czkawka?

You can inspect locally available files, but cloud placeholders and sync behavior complicate scanning and deleting. Use a local backup and pause before processing a sync root.

What to know before you begin

You can inspect locally available files, but cloud placeholders and sync behavior complicate scanning and deleting. Use a local backup and pause before processing a sync root. 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: Can I scan OneDrive files with Czkawka?

  1. Check which files are actually available offline.
  2. Select a small locally synced folder, not your entire OneDrive root.
  3. Review duplicate groups with attention to shared and synced paths.
  4. Check OneDrive's recycle/version history plan before any deletion.

Important limitation

Before changing files: Deleting a synced file locally may remove it from other devices too.

How to verify the result

Verify the same retained files are accessible in the cloud and on another device. 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.
