no htdocs in folders window

When I want to upload a new page to my website, I drag it to the htdocs folder in the Folders window.
I've just added a new domain name to my smartftp account and I don't have an htdocs folder there, just the host name, then 'logs' then 'traffic.html'.
I've tried dragging the new page to these three folders but it doesn't work.
What should I do to upload a page to this website? Should there be an htdocs folder?
Thanks in advance for any help--I've posted here before and always had helpful answers.
