[open target window]

I'm trying to change the target window that appears when I open documents in
Word 2007. For example, I would like it to open in my network folder where
all my documents are stored. It always opens in the default "my documents"
folder. I've been able to change this easily in other versions of Word, but
Word 2007 looks so different than other versions, I've not been able to find
the function. I don't know if it's even possible. Any information would be
helpful. Thanks!!
