Looking in the wiki I have seen that the nomenclature is country-town, if this could be the area covered this file can be es-Alava, Álava is the region, also, the complete name of the town is Vitoria-Gasteiz, if this broke the nomenclature of the file because the second '-' could be changed to es-Vitoria without problem because won't be confusion with another town in Spain.
