Thanks! I tried it on an unsaved copy of one of the chapters. I'd be unlikely to lose a whole copy because I break everything up into chapters, flashbacks, and then also the original story... I have a few ways of keeping the data backed up. (Plus, I have several copies of the folder on both my computer, flash drive, my other computer.)

It took a while but it worked - the example has nothing but Zs now hahaha.
