installing prestashop 1.7.2 via cyberduck (using mac) on dream host

[Serena341]

Hi I need help installing prestashop 1.7.2

 

I ve created a connection with Cyberduck via sftp cause my serveur dream host uses this protocol, but on the Cyberduck tutorial I found they use ftp and they create a www file under "more options/ path", I followed the same instruction and the file didn't t get created, so now I m supposed to drag the unzip prestashop file under the root of my website, but I don t find the "/web" folder, I have only the "/" folder with many files inside, I don t know which one to drag the prestashop file to....  is it the file "root"? I ve tried to open, I get "listing directory root failed"....
