Where your files live

Your book is a folder of plain files on your computer. You choose where it goes.

Updated October 15, 2026

A Bunsho book is a folder on your computer. Each chapter is a file inside it, readable without Bunsho. There is no hidden database and no copy kept on our servers.

Choose where a new book goes

  1. Choose File, then New Workspace.
  2. Pick a place and a name in the window that opens. The window starts in a folder called Bunsho in your home folder, with the name "Untitled Manuscript". Change either.
  3. Click Create.

Your book is a folder whose name ends in .boworkspace. Chapters are inside its pages folder. Things Bunsho remembers about your story, such as World and checks, are kept in the same folder, so they travel with it.

Open a book from another place

Choose File, then Open Workspace..., and pick the .boworkspace folder.

Move or copy a book

Close the book first (File, then Close Workspace). Then copy or move the whole .boworkspace folder in Finder or File Explorer. Always move the whole folder, not single files.

Tip:Because it is an ordinary folder, tools such as Time Machine, Dropbox, iCloud Drive or a USB drive work on it. Bunsho does not run its own sync.

Prefer a Word file? You can export at any time. See Export your manuscript.
