Vista - moving from XP Home to Vista Home

I have set up Microsoft Office 2003 on my Vista laptop. I have found where to save my templates, but cannot find the folder to save my custom dictionary and autocorrect files. I have seen references to an AppData folder, which I do not see. I also have seen references to a "roaming" folder, which I do not see. Does anyone know where I can locate the folder for these 2 items? Thanks!

AUTOCORRECT:
Click the Office Logo in the upper-left hand corner of any Word page, then Word Options.
Select: the Proofing tab.
Select: AutoCorrect Options. When the window opens you'll enter the text you created for your phrase in the "Replace:" box.
Then you'll enter the whole phrase in the "With:" box.
Click: the Add button near the bottom of the window.
Click: OK to close the AutoCorrect window then close Word Options.
