Pedigree Forge offers two modes for storing your project:
The project is saved as a single .ped file, like a word processor document. You must save manually (or rely on auto-save). This is suitable for most users and smaller projects.
The project is stored in a database that saves changes continuously as you work. This is better for larger projects where the file would be slow to save all at once.
To switch modes, use the options in File on the menu bar. Switching from document to database mode converts the file; switching back creates a document copy.
Note — In database mode, there is no "save" step — changes are written immediately. The undo function still works within a session.
