It is saved in XML format (.vpc file extension), as simple as possible, but it already has 817 lines of text. Writing the procedure to load all those values will be a little nightmare… if the XML library I use can handle that…  So the progress is:

1. Open project: underway;
2. Save project: complete;
3. Save project as: planned.

Notes to myself…
For a saved project reduced to “essentials”, in other words, saving only what is different from the initial configuration of the board, I need to be able to revert anytime to this initial status. Right now, this status is achieved only at startup time, then no way to revert to it, only by restarting the VPC application. I will tinker with this later as I need this initial status when I create a new project without restarting the entire application. Well, it is easy to do, but I’ll think about a “simplified” saved project… CubeMX already has this. But not urgent…
