I have some LRF files, though, that have incorrect metadata, so Calibre isn't looking at the filename to determine the values (is that right? If there is metadata present it doesn't use the regexp). The author and title are reversed in the actual metadata. Is there any other way to fix the data without doing:
Hit 'E' to edit individually
Mouse click "Swap author and title" button
Enter to save record
...for each book?
