Remote differential compression (RDC) is a client-server protocol that can be used to efficiently update files over a limited-bandwidth network. RDC detects insertions, removals, and rearrangements of data in files, enabling DFS Replication to replicate only the changes when files are updated. RDC is used only for files that are 64 KB or larger by default. RDC can use an older version of a file with the same name in the replicated folder or in the DfsrPrivate\ConflictandDeleted folder (located under the local path of the replicated folder).
