Not sure I would want to do all the work to write the code to modify your 1300 files when there is a program that can do it for you. The other day, I used the Professional version of Infix to batch modify almost 100 files using its "Find and Replace in Files" feature. It works great. I have evaluated other programs in hopes finding an find and replace functionality similar to Microsoft Word. Infix was the only one I found that can do it.
