Albert,
Just a head's up that on windows 10, mapped drives are regularly polled and reconnected behind the scenes, which can cause momentary loss of connection to files on the mapped drive. Save yourself days of fun-filled investigation by using unc paths rather than mapped drives!
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
