If you modify svsinghs step 10 as follows:
perl.exe c:\work\perl\qaHelpTitles.pl "%1"
Then the name of the directory that you right-clicked on to run the script will be supplied to the script as $ARGV.
A word of caution though. The path supplied is one of those dratted shortened thingies. It's been so long since I encountered one of these that I forgot what they are called?. These work okay for many purposes, but are likely to confuse some things. There's probably a simply way of retriving the expanded version from the shortened one, but I haven't looked that up yet.
