Re: VM size increases 400% when uploaded to ESXi

I assume that you used a sparse vmdk format on Workstation with a nominal size of 100gb.
If you want to convert the Workstation format to a thin provisioned ESXi format use a tool that gives you full control over the output format.
You could do this by uploading the VMDK via WinSCP and then convert it via
vmkfstools -i uploaded-ws.vmdk thin-esxi.vmdk -d thin
