KEYBOARD SHORTCUT: None

FUNCTION: Saves a project's data files in a specified subfolder other than the current project folder

NOTES, SPECIAL CASES OR EXCEPTIONS: This operation opens up the "Save Data" dialog with the default file path set to a subfolder named "Simulation Data" under your current project folder. You can choose the default subfolder name and location or change the name or browse to another location on your hard drive. it is important to keep in mind that before every simulation, EM.Cube deletes all the data files in the current project folder. In order to preserve your simulation data, you have to save them in a different folder other than the project folder.
