Workaround/ Action Plan

The issue occurs because of access rights to the source folder.

To solve:

1. Check If the folder is in use by another user.
2. Run CLI with admin rights.
3. Check if you can rename the folder.
4. Rerun the CLI scan,
5. If you still see the error don't hesitate to contact CAST Support.
