A host computer system obtains a request for an aggregated view of content in a computer network corresponding to a criterion. The host computer system queries networked computer systems to identify data objects according to the criterion. Each responding computer system provides an identification set of specified data objects that are stored at the responding computer to the host computer systems. The host computer system merges the identification sets to form the aggregated view of content to a user. If a specified data object is replicated to networked computers, the host computer system provides one instance of the specified data object in the query result. Consequently, concurrent utilization of file synchronization and the aggregated view of data objects are facilitated. If a specified data object is stored at the host computer system, the host computer system blocks querying of networked computers about the specified data object.
