Why convert MPP to GAN?
Microsoft Project licences are expensive, while GanttProject is free and runs on Linux where Project has no native version. Recipients using GanttProject as their primary tool need a .gan file to open, edit, and update the schedule without any paid software.
How to convert MPP to GAN
GanttProject FREE
Open GanttProject and use File > Open to load the .mpp; review the imported tasks and links, then go to File > Save As to save with the .gan extension.
