Primitives are not stored as an entity on disk, but are directly created by code residing in LabVIEW.exe. The LabVIEW menu palettes then hold links to those pirimitives. Creating primitives not made availabe through the menu palettes is a function of the Create Object primitive that is part of the scripting palette extension. This node has a ring input that contains all the primitives and controls, the LabVIEW executable contains internally.
