World Music Jam Pack query

[dogbone]

There is supposed to be 12 gigabytes of stuff and I was going to purchase a copy on ebay but the seller says there is only one disk which obviously won't hold 12 gigabytes. I was wondering if anyone knows if it comes on 2 disks and therefore one is missing or if it is somehow compressed and fits on a single disk.

thanks

The Jampack world music disk?

And can you tell me if the 12 gig is on two disks or somehow compressed onto one?
