I am new to RoboHelp. I am trying to copy one of the sample files and save it as something I can edit, but I don't see a Save As menu option. Can this be done in RoboHelp?
Simply copy the folder with the sample project and paste it somewhere else.
You can edit the one in My RoboHelp Projects without worrying as if you mess it up or simply want to revert to clean copy, you can copy the project from Program Files. Don't try to use it there though.
It's explained in the About RoboHelp project itself.

Once you copy and paste the folder as Peter say, you can then open the project and change the title in Project Settings.
You probably also want to go into each output preset and change the output titles, output paths, and publish destinations.
