O.K. This is a stupid question. I’m new at running a website, and I was with another host briefly. There the control panel had a manage files area where I could see the directories, delete files, find what folder the word press themes are in etc. I know I need FTP to upload, but how do I view the hierarchy, delete, see what files are in what folders etc?
Go to the Panel for Users -> Manage Users and click WebFTP for your user. It has a similar look to web-based file managers.
Or you can user your own FTP client:
Filezilla is a good one that’s free.
