Albert Eugene Barnes appeals the district court’s order accepting the recommendation of a magistrate judge and dismissing Barnes’ § 2241 motion. The magistrate judge recommended that relief be denied and advised Barnes that failure to file timely objections to this recommendation could waive appellate review of a district court order based on the recommendation. Despite this warning, Barnes failed to object to the magistrate judge’s recommendation.

*570 The timely filing of objections to a magistrate judge’s recommendation is necessary to preserve appellate review of the substance of that recommendation when the parties have been warned that failure to object will waive appellate review. See Wright v. Collins, 766 F.2d 841, 845-46 (4th Cir. 1985); see also Thomas v. Arn, 474 U.S. 140, 106 S.Ct. 466, 88 L.Ed.2d 435 (1985). Barnes has waived appellate review by failing to file objections after receiving the proper notice. Accordingly, we dismiss the appeal. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid in the decisional process.

DISMISSED
