These files are for adding blank notes pages to your character book. All you need is a piece of elastic string.

Tie the string into a loop, print as many blank pages as you want (front and back), fold them in half, and then place the loop around them. slide your character sheet into the loop, and then place the whole thing back in your character book.

If you didn't buy one of the physical books, you can easily make your own out of cardstock, leather, or anything you want. Here's a video: https://www.youtube.com/watch?v=Ug0DK07LduI
