You are comparing Spiders to Hedgehogs here.
Topics refer to individual HTML pages that are part of your RoboHelp project. Books are a means of organizing items inside your Table of Contents.
Are you asking if you may copy TOC structures? If so, the answer falls into a huge gray area. You could certainly import a TOC into your project. But does the project the TOC was originally part of have the same topics in the same folder structure? If not, why would you go there?
thanks for the answer.
I'd like to copy an actual topic into another RH project. Not the TOC.
Is that possible?
I tried cut and paste and that didn't work.
