Many thanks for your reply. I suspect I posed a wrong question. The vmdk managed by an ESXi 6.5 host) disk is thin and the size is 300 GB. There is a partition inside and the size in 100 GB. I want to reduce the spze of the vmdk disk from 300 to 200 GB. Can StarWind V2V Converter help? Or, is there ...

I need to convert a thin vmdk disk by reducing the size.
The size of the (thin) vmdk disk is, let's say, 300 GB, while the Windows partition inside it takes only 100 GB.
Can I use StarWind V2V Converter to convert my vmdk disk to a smaller size?
Regards
