if you have powered it off.....there should be now space in use by the VM SWAP file, and also the virtual disks should not grow any more...<br />
<br />
Make sure the virtual machine disks are not connected to any backup appliance...<br />
<br />
1. Right Click the VM - Snapshot &gt;&nbsp;Take Snapshot (enter name and description!)test<br />
<br />
2. wait 60 seconds<br />
<br />
3. Right Click the VM - Snapshot Manager &gt;&nbsp;Delete ALL<br />
<br />
4. BE PATIENT whilst it's merged! (deleted!)

did you follow my procedure above ?

I followed it to the letter! &nbsp;I was even patient....anyhow, I'm trying again. &nbsp;How much space is needed to get a snapshot? &nbsp;If I have a 100GB data store, how much of that can I use to create a virtual disk?

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
