How to get VmDiskFileInfo.CapacityKb from .vmdk file?

How to get VmDiskFileInfo.CapacityKb from .vmdk file?
I found a TODO here(host_datastore_browser.go 89-91). Does it means Govmomi is unable to get VmDiskFileInfo.CapacityKb?
Or is there a other way to get VmDiskFileInfo.CapacityKb?
thanks!

That TODO is part of the simulator, do you need that or the client side against a real vCenter?
For real vCenter, you can use VM's devices VirtualDisk.CapacityKb, for example:

% govc device.info -dump -vm MinIO disk-*
...
    BaseVirtualDevice: &types.VirtualDisk{
...
        CapacityInKB:    16777216,
...

Or you can use HostDatastoreBrowser to get a .vmdk's capacity directly, for example:

% govc datastore.ls -l MinIO/*.vmdk
16.0GB  Wed Mar 13 17:31:51 2024  MinIO.vmdk

% govc datastore.ls -json -l MinIO/*.vmdk
[
  {
    "datastore": {
      "type": "Datastore",
      "value": "datastore-12"
    },
    "folderPath": "[datastore1] MinIO/",
    "file": [
      {
        "path": "MinIO.vmdk",
        "fileSize": 17179869184,
        "modification": "2024-03-13T17:31:51Z",
        "owner": "root"
      }
    ]
  }
]

@dougm thks for your reply
The last way seems to get the physical capacity, and the first way needs that the disk was attached to one vm.
But I want to get the logical capacity for vmdk which is not attached to any vm.
