The web root is the folder where the website files for a site are stored. Each site under your host gets an unique root folder.
The root folder is placed under the sites username. Inside the web root folder you’ll find folders like \logs, \public, \private and more.
Site Root Folder
The most important folder is the /public folder as this contains your actual site. In other words, your site root folder is the same as the /public folder in your web root. This is where you are supposed to place all your files you want accessible from the internet. In other words, this is where you’ll find your CMS’ files.
At your top-right here, you’ll find an example of what your site root could look like when you have WordPress installed, for instance. But in reality, this could be any other collections of files and folder from another CMS.
If you have any files you do not want accessible from the internet for storage or otherwise, you should store them in the /private folder.
Web Root Directory
The Web Root Directory is the path of the location of your Site Root folder. You can find this information is the Server Login Information tab per site in the Control Panel. It’s listed at the bottom under Web root directory. You’ll need this information, for instance, when you’re adding cron jobs to WordPress or WooCommerce.
Log files
Inside your Web Root folder, you’ll find a the \logs folder which contains various log files. Learn more about the ErrorLog file and the AccessLog files inside that folder.
