Yes,
When RoboHelp creates the files it defaults to the project
name for all of them. I don't know how to change this in RoboHelp,
but you can rename the .hhc file in Windows Explorer and then open
the .hhp file in Notepad and you will see a link to the .hhc file.
Change that too and then open the project in Robohelp from the .hhp
file. It will then correct the RH project.
There is probably an easier way to do this from within
RoboHelp, but I use an ancient version and couldn't tell you ho to
do it. Hopefully, someone else will add to this. Otherwise, the
above method will work.
