Key - Ultracopier

Ultracopier uses intelligent memory buffering and asynchronous I/O operations to achieve significantly faster transfer speeds than native copy routines. It dynamically adjusts buffer sizes based on the source and destination media (HDD, SSD, USB, network drive), reducing seek times and maximizing throughput. Users can manually set buffer sizes for fine‑tuned performance.

If we reinterpret "key" as keyboard shortcut, then Ultracopier has a powerful set of keys that turn you into a file-transfer ninja.
