Hi,
as marcelo said, the thin disks works at VMFS partition level. Thin disks doesn't exist outside a VMFS partition.
For example is you run "df -kh" you will see the real disk space usage (allocated) of the VMFS partition. In other words you are seeing the total amount of disk space used by the vms' thin disks.
Anyway, is you run in the busybox "ls -sh" (instead of "ls -lh") you will see the real disk space usage of the thin virtual disk of a particular vm (vmdk).
But the problem is that tools like winscp don't see the allocated disk size of the thin disks. This tools sees the reserved vmdk's file size. Then it copies all the disk file size as thick disks. And of course, the target file-system partition that will hold the thin disks, doesn't support thin disks.
A thin disk with 3 GB of real data (allocated) and a reserverd size of 10 GB is copied over the net by Winscp as a 10 GB disk.
