I am migrating from a Dreamweaver forced working environment to a free-of-choice one. That said I must say I was rather enthusiastic about being able to use Dreamweaver PDT.
I use FileSync its an ellipse plugin. In zend studio 9 its already installed you just need to enable it.
Once you have enable it do the following
right-click on project --> Properties --> File synchronization
then just add the project folder. and the default target path locate your target folder
(my target folder is my dev server i just map it to my local drive)
