Abstract: Embodiments are direct to managing file systems. Alternate data streams (ADSs) of an object in a file system may be modified based on a request from a client and metrics associated with the ADSs may be modified. Values for reconcile fields associated with the object may be set based on the modified metrics such that the object with the modified ADSs may be included in a reconcile list. And, such that an acknowledgment of the request may be provided to the client. A reconcile engine may determine a parent object of the object. The object may be reconciled and the parent object may be placed on the reconcile list for reconciling in turn.
