Folders and Scenes
Your manuscript is built from two building blocks:
Folders are structural containers. Use them for whatever levels your story needs — acts, parts, chapters, sections. Folders can nest inside other folders to any depth, so you can model whatever structure makes sense for your project.
Scenes are where the actual writing lives. Each scene holds its own text. Scenes always live inside folders.
A novel might look like: Act I → Chapter 1 → “Opening scene”, “The inciting incident”. A nonfiction book might be: Part 1 → Chapter 1 → “Introduction”, “Key argument”. Herbert doesn’t impose a structure — you build what fits.
