The present disclosure is related to methods, systems, and machine-readable media for deleting snapshots. A deletion process can be performed responsive to receiving a request to delete a snapshot of a virtual computing instance (VCI) in a file system. The deletion process can include performing a first file comparison between the snapshot and a previous snapshot to determine first extents exclusive to the snapshot, performing a second file comparison between the snapshot and a subsequent snapshot to determine second extents exclusive to the snapshot, performing a third file comparison between the first extents and the second extents to determine common extents, wherein the common extents are common to the first extents and the second extents, and deleting the common extents from the file system.
