Rule 2220. Entry and filing of order; service. (a) Entry and filing.
An order determining a motion shall be entered and filed in the office
of the clerk of the court where the action is triable, and all papers
used on the motion and any opinion or memorandum in writing shall be
filed with that clerk unless the order dispenses with such filing. When
a statute or civil practice rule requires such filing and entry in a
county other than that in which the order was made, the party prevailing
on the motion shall file the order and the papers used on the motion
with the proper clerk after receiving them. If a party fails to file any
papers required to be filed under this subdivision, the order may be
vacated as irregular, with costs.

(b) Service. Service of an order shall be made by serving a copy of
the order.
