Hi, all.

I am lumping a few questions together. I have finished reading the Calibre manual and feel better acquainted with the program.

1) Can someone please explain the concept of Polish? How is metadata used to generate more metadata in a way that is different from searching for metadata (and generating it from) online? Also, I continue to get an error message when trying to use the Polish command with Epub and AZW3 ebooks.

2) What happens when separate book records of the same book that is divided into different formats are merged and then exported? Does Calibre make an automated decision about which format to export or is there a dialogue window allowing the user to choose which file type to export?

3) Where is the "Add subcategory" command located? When I right click within the Tags section, I don't see any such option. [I have attached a screenshot to show my view.]

4) I apologize if this is a stigmatizing question (it's not clear to me if this is a file management question that is being explicitly addressed in the FAQs section), but is it possible to change the default location of the Calibre library to an external drive? (I am concerned about running out of space on my computer.) Or does this qualify as tampering with the program's innate coding?

Thanks for the help!
