Rule 3. Files and exhibits.

(a) The court is the custodian of all court files. Files shall not be taken from the court without the consent of the judge.

(b) Every exhibit placed on file or offered in evidence shall be held in the custody of the court. Unless there be good reason why the original of an exhibit should be retained, upon application, the court may order a copy filed in its place. Public records offered in evidence may be withdrawn at the conclusion of the hearing on order of the court.

(c) Exhibits may be withdrawn by the party offering them thirty days after a judgment has become final. Forty-five days after a judgment has become final, a party may apply to the court for an order to dispose of exhibits, and shall notify the other party of said application. Twenty days after mailing of said notice the court may enter its order authorizing disposition of exhibits.
