Last week I posted the excellent news that the Robocopy in new versions of Microsoft Windows is multi-threaded and thus much (much!) faster. Then I tried to actually use it on a Windows Vista machine. Redmond, we have a problem. It turns out that only the “6.1” versions of Microsoft Windows (Windows 7 and Windows Server 2008 R2) include multi-threaded robocopy.
Robocopy is the best tool to move data between NTFS filesystems but was never very quick. Windows Vista, Windows Server 2008, and later versions include a new version of Robocopy with performance tweaks including multi-threading that speed things up dramatically.
