Change page size for hundreds of documents

[Steve_D]

Hi
I know a bit about Word but am totally new to VBA, but I think it might help here.
I have 500+ Word documents that have been set up with Letter page size and I need to change them all to A4. Is there a way to do this with VBA?

I also need to change the footers in all the documents. I have previously set up a word macro to do this (one by one), but if this could also be done more efficiently in VBA, please let me know.

Is there a good resource where I can find this kind of information?

Cheers
