How it works

  1. Select local files or folders in File Explorer.
  2. Press Alt + Space and type “Find Duplicate Files”.
  3. Review the scan scope. Large folders take longer; scan limits and inaccessible items can restrict results.
  4. Start the action and check the result.

A practical example
