First, great software! Second, I've looked for the answer to these questions, but can't find answers. Third, thanks in advance for any help!

Finally, here's my problem. I installed Mezzmo and added several folders. I have my movies broken into folders by category. All of the movies in my Science Fiction folder were tagged in Mezzmo as an Outer Limits episode that I don't even have. All of the movies in my Comedy folder were tagged by Mezzmo as a Pettycoat Junction episode that I don't have. I'd rather not have to go file by file to remove and correct the incorrect metadata.

1) Is there a way to do a batch reset of metadata on several files?
2) Is there a way to add metadata to files as a batch or group?
3) Is there a metadata scraper whose results/data can be imported into Mezzmo?

Again, thanks for any help.
