Knowing your website's root directory can give you information on where you can deploy its files and bring it online. On a typical cPanel server, which we offer at HostArmada, the primary domain name's root directory is the "public_html" folder located in the user's home dir. Here is the absolute path there:
/home/user/public_html/
If you have a plan which supports addon domains, you will have the option to assign each addon domain to its unique directory in your account. For example, you can create a directory "addon_domains" within your home folder and define each addon domain's root directory inside:
/home/user/addon_domains/site1/ /home/user/addon_domains/site2/
Here is a useful tutorial you can use to manage your addon domains:
