How do I replicate a RoboHelp project?

I used RH way back when, and I thought that, back then, I could name the folder where a project is stored in the .hpj file. Am I remembering incorrectly? I used that capabilty to maintain multiple versions of a Help project and to replicate projects and modify the HPJ to point to the folder I wanted to work with/compile.

I'm working with RH 11. Can I this with an .xpj file?
