Windows 7 has included a neat utility called robocopy. If I remember correctly this was a utility back in Windows Server 2003. This is an advanced copy paste tool :) (lack of term hehe) where you can define options such as copy everything but not empty subdirectories, cool huh?
But wait, there's more! in Windows 7, you can copy your files in multi thread! just add the /MT switch and define the number of threads and instant multi threading copy!
So to do that, the command syntax is “ROBOCOPY <Directory that will be copied> <New Directory> /MT:<Integer number of threads to use>” just for kicks I used 120 its the maximum thread that we can give and there! instant copy!
I started to copy 8:46:17 and the command ended 8:46:28. The whole directory is 230.31 MB, now you do the math :D
