Quite right you are, thanks for pointing me to that. I wasn't 100% sure if the directory would be moved or recreated - as the answer is "moved" then my caution on that was unnecessary.
However as you have a workaround of adding as a zip then that is even better. The only reason I did not suggest that is Calibre uses a zip format for storing html files in. So provided you don't intend to have an html format of a book and an audiobook format then you should be ok. Also of course it also means you have to unzip your audio files each time to play them, where I thought you may have been wanting to keep the files unzipped to use Calibre to send them to a device or something.
However if that solution does what you need then it's all good
