A simple question but best to ask. To find this file [cscart_dir]/app/addons/paypal/controllers/common/

Its through C-Panel-File Manager-Public_html?


by default (if you have one site in cPanel) - yes

I suppose you better provide more details on what you would like to find out. Now it's not quite clear from you message.

If the root directory of your CS-Cart installation is public_html, then yes
