How to remove footers all Excel docs at once.
 

I have many Excel files within one folder. How can I globally turn off the
footers on each of these files within this folder? Do you have to prieview
each one separelty and select "none" for each? I just got a new computer and
the files seem to be defaulting with the filename, date, time and page#. I do
not want these to print. Help!
