I am using ArcMap 10.2 and an ArcPy script tool to create an XY Event Layer from a text file and then save the layer to a .lyr file. This works, but I also want to load a hyperlink file and apply it to the layer automatically. I tried using UpdateLayer, but this just replaces the entire layer, it doesn't keep the same source data.
Does anyone know if there is a way to load a .hlk file using ArcPy?
