Use one of the following methods to save an individual VI:
Select File»Save to save changes to an existing VI in its current disk location or to save a new VI. If the VI is new, specify the name of the VI and its location in the Name the VI dialog box.
Select File»Save As to save a copy of the VI in memory to disk with a new name you choose. After the save finishes, the VI in memory points to the new version. In addition, all callers to the old VI in memory now refer to the new VI unless you place a checkmark in the Save a copy without updating callers checkbox. If you enter a new name for the VI, the disk version of the original VI is not overwritten or deleted.
Select File»Save with Options to display the Save with options dialog box, where you can save VIs with passwords and without block diagrams. This is useful for distributing VIs or for making backup copies. You also can save a VI for use in a previous version of LabVIEW.
