What to know before you begin

Use the Big Files mode to rank large files in the folders you select. This helps identify archives, exports and videos that are candidates for manual review. 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 do I find the largest files with Czkawka?

  1. Select a drive or personal folder.
  2. Run the large-file search and sort descending by size.
  3. Identify whether files are backups, media or active project data.
  4. Move obsolete files to another backup location before permanent deletion.

Important limitation

Before changing files: The biggest file is not automatically safe to delete, especially virtual disks and backups.

How to verify the result

Verify Windows free-space readings and access to retained projects. 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.
