Robocopy has been part of Windows for a little while now. It's an excellent command line tool for copying files around if you haven't seen it before.

New to Windows 7 (and Windows Server 2008 R2) is the /MT option. This causes robocopy to operate in multi-threaded mode which realises a noticeable performance boost. It's well worth trying it next time you have to copy a large number of files around.

e.g.

robocopy \\server\share\folder c:\users\tblack\downloads\folder /tbd /s /z /mt

You can see a full list of the available options by typing

robocopy /?

within a command prompt window. This is the help for the /mt option.

/MT[:n] :: Do multi-threaded copies with n threads (default 8). n must be at least 1 and not greater than 128. This option is incompatible with the /IPG and /EFSRAW options.
