AFFIRMED.
Before RUSSELL and HALL, Circuit Judges, and SPROUSE, Senior Circuit Judge.
PER CURIAM:


1
Gregory Louis Charles appeals the district court's order dismissing this action brought under 28 U.S.C. § 2255 (1988).  Plaintiff's case was referred to a magistrate judge pursuant to 28 U.S.C. § 636(b)(1)(B) (1988).  The magistrate judge recommended that relief be denied and advised Plaintiff that the failure to file timely objections to this recommendation could waive appellate review of a district court order based upon the recommendation.  Despite this warning, Plaintiff failed to object to the magistrate judge's recommendation.


2
The timely filing of objections to a magistrate judge's recommendation is necessary to preserve appellate review of the substance of that recommendation where 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);   United States v. Schronce, 727 F.2d 91, 93-94 (4th Cir.), cert. denied, 467 U.S. 1208 (1984);   see also Thomas v. Arn, 474 U.S. 140 (1985).  Plaintiff has waived appellate review by failing to file objections after receiving proper notice.  We accordingly affirm the judgment of the district court.*  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 the decisional process.

AFFIRMED


*
 Four months after the government responded to Charles' § 2255 motion, Charles filed motions to amend the motion and for an extension of time to file a memorandum of points and authorities in support of his § 2255 motion.  The magistrate judge denied the motions and the district court affirmed.  Based on the magistrate judge's reasoning, we find that Charles' motions were properly denied
