installing wordpres on one.com

Hi, Just installed wordpress on my hoster one.com using Filezilla I dragged the unzipped wordpress folder to a folder called / which I believe is root. Either way it’s the only place to drag it to.

So it installed and I went through the process on a browser to install.However, this has installed WP on a subdirectory so my site is handy4landlords.co.uk/wordpress

So how can i move this but even better how do i just load the files straight to root.Thanks.
