I have a .doc around 5000 pages all in A4 page size,
now I wanna make it ALL into A5 page size but same font size,
but the software said it can't be done when I hit "Confirm" at "Page Setup" after set the paper into A5.

Questions:
1. How do I solve this problem?
2. Even it's done but I find that some sentences are going over the page,
which means they will be disappeared after printed out, is there an auto-break-sentences or auto-break-line function?

Thanks!
