Download huge multiple files on mac

Hello, For Week 3 of the 4th course in the specilisation, is there a way to download the files into my macbook? I saw instructions online but none seem to work for me. It will be great if there is a step by step instructions. Thank you

From the Notebook “File” menu, there is a download button.

Hello but some of the folder contains alot of pictures which i cannot download. Is there a quicker way to download

Sorry, I do not know.
