Pet Peeve Open Folder

I have a nuisance issue. For the last several versions of dreamwweaver when ever I boot the program there is an old folder that is always opened in my files list and I want it to remain closed. It is the same folder and I can;t see any setting that would default to it being the opened folder. Just a nusiance that drives me a little batty. IS there a way to set folders opened or closed?
