What does Core4X.exe do?

Hi,

Just wondering what this file does, in the Steinberg/Cubase 5 directory. I clicked it and Cubase opened, so is a file that checks for 4 cores and gets Cubase to use them if available?

Just ordered Cubase 6, hence was looking in this forum. I’m guessing that Cubase 6 will have the same file?

Regards,
Steve
