User. VPJ files tell the program where to find source files and what to do with them, they are not playable.
Save Project Files AS routinely, giving them a unique # or name, so as not to overwrite earlier saves. Using Save Project or Save Project Files will overwrite.
Then, just by double-clicking the VPJ, the project can be restored to the state it was in when the file was saved. Do not delete or move source files.
