Where should I upload the files for my addon domain?

When you create an addon domain, the webroot directory is created for it. Thus, you can visit your cPanel -> Addon domains and next to your addon domain name you should be able to view its webroot folder. Then navigate to this folder with your FTP client and upload the desired files there.
