How do I copy my photo book projects to another computer?

The project is listed in the user folder on your computer.

In Windows PC:
C:/Documents and Settings/USERNAME/My Documents/Profotonet Album Designer Projects

In Apple:
Macintosh > Users > USERNAME > Profotonet Album Designer Projects

Copy this folder and, on the new device, paste it in the same place. You will have to show the software the location of the photos the first time using the new device.
