Hi Patricia
As for the folders and files, consider everything you find in
the WebHelp folder to be needed. Yes, you will find some files that
aren't used. The thing is, WebHelp has some built in fall backs.
Some of the files are needed in case it switches from one display
method to another. Weeding out what isn't needed for certain
situations will likely take far more time (and time is money) than
it will "cost" in additional disk space if you just accept what is
there.
As for the calls you need to make to establish links, there
is more on that at the link below.
