Projects & files

Name the project, pick your print vendor and album size, and choose where it saves. BookProofs creates a folder for your project.

Pick any folder you like and the app remembers it from one session to the next. Leave it alone and it uses your system Documents folder.

The .bp project file, a thumbnail cache built when you import, and a preview cache built when photos land on the canvas. Automatic Backup project files are also stored in your project folder.

BookProofs writes a backup roughly every five minutes. Open the backup list for a project and click a point in time to go back to the project as it was then.

File > Duplicate for different size copies the project at a new size, keeping the design. Pick the size, rename the copy, save it in your normal projects folder. The same flow moves a project to another vendor or a different aspect ratio. Going horizontal to horizontal, portrait to portrait or square to square usually lands almost identically; changing the aspect ratio changes how your photos are cropped, so BookProofs warns you to review the updated design on new project creation. To duplicate a project to the currently selected vendor and size, or to rename it under a different name, use File > Save As instead - it is placed in a new folder and also leaves the original project untouched.

On by default: the project saves each time you move to another spread.
