the configuration folder path for CS5 is almost identical to the path for CS4, except you substitute "Dreamweaver CS5" where the path says "Dreamweaver CS4"
instead of:
Adobe/Dreamweaver CS4/en_US/Configuration/
use this for CS5
Adobe/Dreamweaver CS5/en_US/Configuration/
or for CS5.5:
Adobe/Dreamweaver CS5.5/en_US/Configuration/
