A while back I created a Dreamweaver plugin called Blackbaud Sphere CMS (http://www.adobe.com/cfusion/exchange/index.cfm?event=extensionDetail& extid=2430523). Anyhow during install it provides the user with the options select a custom save directory for KDF files. This directory is referenced when creating template files later on. It was working perfectly fine in Dreamweaver CS4-CS5.5 on OSX and in CS6 it doesn't remember the users directory selection. Haven't checked to see if this was occuring in Windows yet. For now I'm trying to resolve the OSX 10.7.4 with CS6 issue.
See how the token is written below:
<token name="KDF" prompt="Descriptor Files (Save all .KDF files here)" default="$dreamweaver/configuration/Blackbaud/Templates/KDF" />
I should note that it does crete the default directory however it is also not recognized.
