How do I restore C3 project tabs on new computer?

On my old PC I had ~25 different editor tabs open in my project (event sheets, layouts, files, etc). Just got a new PC and I copied all my C3 project files over, but when I open the project only the main layout and its event sheet open up in tabs. Is there a way to restore the project tabs and formatting that I had on my old PC? Using Chrome fyi...

Thanks
