adding a partition to the existing harddisk

Hi,

I created a VM with 80GB VHDX ( this is the only partition C drive ) and installed OS on that.Now I would like to create one more partition (D drive with 80GB). how can I do this ?

while creating the VM, on the host I created the vhdx in a folder eg. dcserver. Can I create the new vhdx or vhd on the same folder ?

Thanks in advance
