How to find the Content folder for a site?

Ok, this sounds kind of ridiculous, but I’m now working for a company that hasn’t updated their website in several years, & whoever did it last isn’t contactable anymore. I can log into the Kirby panel on their site, but can’t locate the core content folder. Any suggestions how to locate it or regenerate this folder somewhere I can control/access?

You can’t access the content folder through the Panel (only the pages made available through the Panel). To get at the content folder, you need (S)FTP access to the server. Your client should have the credentials for the hosting account.
