Changing metadata(title and author) in bulk/by macro from filename possible?

Hi.

I'm new here and wasn't sure if this sub-forum is the right place to ask this question.

I have like tons of books in mobi and epub formats and many of them have bad metadata but correct information is always presented in the same way in the filename. For example: "Title - Author.epub"

Is there any way to change metadata of ebooks in bulk/by macro, where data is taken from filename.

I guess it's nearly impossible at those days?

Thanks.
