The exact path to a file or folder in your domain’s hosting plan, is the following:

For Windows Hosting → C:\Inetpub\vhosts\my-domain-name.gr\httpdocs

For Linux Hosting → /var/www/vhosts/my-domain-name.gr/httpdocs

Replace my-domain-name.gr, with your own domain. Add the file or the folder at the end of the path.
