How to access server other folder

Hello friends

For testing, I download & setup CI4 on my local development PC. to set document root path I set up the virtual host. Now my question is if I do this on hosting server then how can I access server other folders. By default, it's not set to PUBLIC folder as a document root. when we request to our domain its point to root path and then if we call any folder then simply call that folder by '/folder-name'. for an example : 

Domain : www.example.com

Folder : ABC

call server folder : www.example.com/abc

now if set document root path to www.example.com/public then how we can access the ABC & other folders ?
