Excel 2010 Changing default Blank Page Settings

In the same advance window there is a line
At startup,open all files in:
You can enter the file address there.

I also found this bit of code

  If MsgBox(Application.StartupPath, vbOKCancel) = vbOK Then
    Shell "Explorer " & Application.StartupPath
  End If

It shows where your startup file is located.
