There is the old painful method but it's free.
There is a script available for Willam van Weelden. It's not free but it is one heck of a lot quicker.

Two good places for help on reverse engineering WebHelp - Peter Grainge's site (grainge.org) & Willam van W - wvanweelden.eu
Thanks all just found it as well, definitely looks the best way if it works. Our previous releases in question are Robohelp 8..
I don’t want to use the forums to advertise, but since Peter started it, I would like to make a remark on your ‘if it works’ statement (I assume you’re talking about the script.)
The script recovers about 95% of your project. Never received any complaints
If my recovery script doesn’t work for you I will either: (1) Make it work or (2) give a full refund.
Thanks for that.
