How to change the default project directory in Netbeans 6.9 for Java SE\ME\EE?
I don't think you can make it module-specific but you can set it as follows:
projectui.properties
file. For me (Windows) it was under C:\Documents and Settings\Catchwa\.netbeans\6.9\config\Preferences\org\netbeans\modules\projectui.properties
projectsFolder=C:\\NetBeansProjects
variable is I think what you want to change.
