Hi,
sorry, we never came around releasing the "scrubber" yet. Hopefully in the future (as we are in the process of restructuring ourselfes, we do not have a timeplan at the moment, sorry.). I like the name, though

Support for metadata is currently very experimental and likely not useful at all (sorry about that).
The only currently supported file-system is NTFS, this is due to the technical limitations regarding metadata and the specific implementation of our file tracking algorithm. Maybe once we open-source the system, maybe someone could write something for ext3?

Best regards,
Martin
