So how did they do this? In today's snail mail I received a physical shipment of SQL2012 on a DVD. On that DVD are "Business Intelligence", "Developer", "Enterprise", "Enterprise Core", and "Web" versions of SQL2012. This disk is formatted with 4.26 GB of space according to Windows.
Copied to a network location the files are roughly 24 GB in size. So how did they fit that all on one DVD? The disc is not blue-ray. Is this a case of "de-duping"?
Needless to say I was surprised by the results. The disk does not appear to be damaged in any manner.
