Just to be precise, it’s not part of the filesystem. It’s implemented on top of the filesystem as a background process that moves duplicate data into a “chunk store” and replaces the files with reparse points that route accesses to the deduplication driver. This is ostensibly to keep deduplication out of the write path for performance reasons. https://learn.microsoft.com/en-us/windows-server/storage/data-deduplication/understand https://learn.microsoft.com/en-us/windows-server/storage/dat...
