block cloning

About this tag
Block cloning is a file system feature introduced with ReFS in Windows 11, starting with the 2024 Update (24H2). It enables fast, near-instantaneous copying of large files by referencing existing data blocks rather than physically duplicating them. This capability is particularly beneficial for developers using Dev Drive, a ReFS-formatted volume optimized for workloads like git clones, package restores, and builds. Combined with Windows Defender performance mode, block cloning reduces I/O overhead and speeds up file operations. The feature is exclusive to ReFS volumes and requires compatible hardware, making it a key improvement for users handling large data transfers or seeking faster build times.
