Best case scenario -- calibre recreates them.
Worst case scenario -- calibre loses metadata permanently. (You can always recreate it however you got the metadata in the first place. Metadata downloads/extract from ebook files -- mmm, fun.)
If those are in an exported folder, you can probably delete them. There is an option to not save them in the save to disk settings.

Thanks a lot!
I've confirmed that
cover.jpg and
metadata.opf are embedded in the Book.azw3 file by copying the Book.azw3 file only to another PC and the result was that Calibre generated the two files again.
