You can save the current state of a virtual machine by suspending it. The suspend feature is useful when you want to save the current state of your virtual machine, and resume the work later from the same state. All documents and applications you were working on will be in the same state as they were at the time you suspended the virtual machine.
To suspend a virtual machine, choose Player > Power > Suspend Guest:
To resume a suspended virtual machine, select the suspended virtual machine and click Play virtual machine:
The state of a suspended virtual machine is stored in a file with a .vmss extension. When the virtual machine is resumed, its state is restored from this file.
