Howard L. Pless, Sr., appeals the district court’s judgment in favor of Defendants in Pless’ civil action and the court’s order denying his motion to reconsider that judgment. For the reasons that follow, we dismiss in part and affirm in part.

While Pless’ notice of appeal designated only the court’s August 22, 2013 order denying reconsideration, his informal brief appears primarily to challenge the district court’s order requiring Defendants to explain their untimely summary judgment motion and its order granting summary judgment in favor of Defendants. However, we lack jurisdiction to review these orders. 1 Because Pless’ post-judgment motion was not filed within twenty-eight days of the judgment, it did not toll the appeal period. Fed. R.App. P. 4(a)(4)(A) (addressing tolling of appeal period pending disposition of certain post-judgment motions); Fed.R.Civ.P. 59(e) (stating time to file motion to alter or amend judgment). Pless’ notice of appeal therefore was untimely as to the court’s underlying judgment and all other orders, except the post-judgment order denying reconsideration. See Fed. R.App. P. 4(a)(1)(A) (providing thirty-day appeal period). Accordingly, we dismiss Pless’ appeal in part, insofar as it challenges the court’s underlying judgment in favor of Defendants.

Turning to the order denying reconsideration, we conclude that the district court did not abuse its discretion in denying this motion, as Pless did not meet the requisite showing for Rule 60(b) relief. 2 See Fed. R.Civ.P. 60(b) (enumerating grounds for relief); Aikens v. Ingram, 652 F.3d 496, 500-01 (4th Cir. 2011) (en banc) (addressing requirements for Rule 60(b) relief, and *213 recognizing that Rule 60(b) motion is not substitute for appeal); Dowell v. State Farm, Fire & Cas. Auto. Ins. Co., 993 F.2d 46, 48 (4th Cir. 1993) (describing required threshold showing). Thus, finding no reversible error, we affirm in part, insofar as the appeal challenges the district court’s order denying reconsideration.

We grant Pless leave to proceed in for-ma pauperis. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.

DISMISSED IN PART; AFFIRMED IN PART.
