A home directory (public_html) contains your website's data on a server. It is a directory for your own hosting account.
To check your root directory, open your hPanel Homepage, and click on Manage. If you have more than 1 website in your hosting account, you can click on the number of websites and on the arrow (→) to go to the hosting management page:
Your home directory can be found in the left information column:
You will see a full path if you hover the cursor over it:
The path might be in 2 formats based on the hosting account you use:
/home/u123456789/domains/domain.tld/public_html
/home/u123456789/public_html
NOTES:
The home directory cannot be changed on our Shared hosting packages due to control panel restrictions. However, it can be changed on a VPS Plan!
