Depositions shall be taken as directed in the court’s order; and shall be otherwise governed by rules 1.708 to 1.713 and 1.717. For the purpose of applying these rules to depositions for perpetuating testimony, each reference therein to the court in which the petition was filed shall be deemed to refer to the court in which the application for such deposition was filed. Unless the court enlarges the time, all such depositions must be filed therein within 30 days after the date fixed for taking them, and if not so filed cannot be later received in evidence.
