I'm not sure that's the case. I went ahead and tested it (I figured I had nothing to lose except some time). By pointing the "Local File" at the first vmdk file (which is tiny - must be some kind of index to the remainder of the actual data/blob files?), the software converted it to a vdhx...

No, they are all part of one vmdk disk. They are used as the disk space grows (it is not all pre-allocated), and the option is available when you create any new disk for a VM in VMWare. Snapshots are a totally different concept. For example, see step #7, here: https://docs.vmware.com/en/VMware-Works...

Sorry for the newbie question. Can StarWind V2V convert a vmdk to vhdx IF the vmdk was created as split files? That is, one virtual disk is actually multiple, 2GB, .vmdk files on the host.

(Testing/trying a conversion from VMWkst 16 to Hyper-V due to poor performance in Workstation.)

Thanks!
