Calibre can add books recursively from a directory hierarchy, and this works
fine. However, during flattening out of the directories, directory information is lost.

Say I have a book in a directory dirA/dirB/dirC/book.pdf. I would like
dirA, dirB, dirC to be entered as tags while adding the book into the library.
Later on searching the tags for dirA would list all books under the directory
dirA. Searching for dirC would list only the books under the directory dirC.

Is there an easy way to do this? I didn't see any feature that would allow
me to do this. Would it be possible to do this with a plug-in? I am thinking
that after adding all the books, perhaps adding entries into the tags table
would accomplish this.

Thanks for any help
