Save location

Hello:

I'm having a hard time finding an answer to this on the
MSKB so I hope someone might be able to help me out a
little.

Is there a regedit to change the save location on a users
computer besides my computer or my docs? I need the 'save
to' to default to her mapped network drive then a specific
folder. E.g.

I:\Sample\Sample2

Let me know if you have a question or need clarification.

Thank you!
