The document root is the folder where the website files for a domain name are stored. Since cPanel allows for multiple domain names in the form of addon domains and subdomains, you need to have a unique folder for each domain.
Your primary domain root folder is the public_html folder. Your addon and subdomain names will be rooted to their own folders inside public_html. After creating an addon domain or subdomain, you can find the document root inside cPanel by clicking on the Addon Domains or Subdomains icon
Tip: Click the document root name in cPanel to go to the correct folder in the File Manager.
