copying vm with 4 .vmdk files yields one small and one large one

I'm copying a large server that has 4 .vmdk files on the source datastore, which is on an iSCSI LUN, and I'm relocating it to an NFS datastore.  I see 4 .vmdk files, but only the first two are size > 0.  The first one is about the right size, but the second one is huge.  I told vSphere to preserve the same type or provisioning (thick,) but I still thought I'd see multiple .vmdk files of comparable size.  Will I end up with just 2 .vmdk files that have any size and pointers to the other 2 for some reason?  Thanks.

if you trying to copy directly , its prefer and recommended by vmware to use Winscp for fast and best results in copying

NFS may only support Thin Provisioning, depending upon the NFS datastore.
