The project files are used to save all project data including:
- All hydrologic objects in each scenario
- All climate data
The locations (on map and on canvas), labels, links and symbols are all saved in the project file.
There are two project files in the project folder. The main project file has the extension of voprj and the secondary one is vdata file. Both files use the same project name. To submit a VO5 model, it is necessary to have both files.
