If you are on a Windows OS you can go to the control panel and in the folder options you can specify to view hidden files and folders. When in the folder options under view in the list you will have a section titled hidden files and folders, you can select to view these files and folders here.
If you are on a MAC OS then you should be able to just navigate directly to the location. Here are the paths for both platforms:
--C:\Users\<Your User Name>\AppData\Roaming\Adobe\Dreamweaver CS4\en_US
--Hard disk: Users: <Your User Name>: Library: Application Support: Adobe: Dreamweaver CS4: en_US
