correction, its a true vmware image, not a virtual machine image
Really!? And just what is that supposed to mean!? (Rhetorical questions!)
the problem is we have here 11 vmdk discs i need only one
so my question was how could i make from this one file CentOS, 64-Bit with all that files one file with .vmdk
So why didn't you just ask/say that in the first place and not all the rigamarole!?
Have a look at: Virtual Machine > Settings... > Removable Devices > Hard Disk (IDE|SCSI) > Advanced options > uncheck Split into 2 GB files
