Disparity between the exact size of a VM's HDD and the Allocation size displayed

We are currently using vCenter 7.1 with VMware Cloud Director 10.1.2 and there is disparity between the exact size of a VM's HDD and the Allocation size displayed both on the vCenter and Cloud Director

Do you have an example (screenshots)?

See screenshot below

When powered on, a swap file is created with the size of the provisioned RAM, so the ~52GB doesn't look wrong to me.

Please explain better, how did the swap file got created and how can we stop that

[a_p_ · Accepted solution]

By default a VM swap file with the size of the allocated memory minus reserved memory is created at power on of a VM.

If you do have sufficient physical host memory, you may reserve some, or all memory in the VM's memory settings.
