That's the key problem for my issue then. I don't want all fields to be overwritten. I want to keep the author and title from filename and the rest of the metadata from the file.
Seems like this cannot be done in Calibre then. I am a bit surprised that this functionality is not available. I would have thought it would be a feature that would be commonly used.
