Macros for Multiple Files to Delete Section Break and Adjust Margins

I have 1750 Word docs that are supposed to be 1 page. However, they each have a section break at the bottom that makes them two pages (second page is blank). When I delete that section break, the margins re-set to Normal.

I need help writing macros that will open the next file in the folder, delete the section break, set margins to Narrow, and Save. Repeat for all files in folder.

I don't know if it makes a difference, but I'm running Word 2010.
