What Snapshot files are created of Virtual Machine?

When a snapshot is created a number of files are created in the directory for that virtual machine.

• <machine name>-SnapshotX.vmsn (Where X is the number of the snapshot taken) This file stores the state of the virtual machine when the snapshot was taken.
• <machine name>-SnapshotX.vmem (Where X is the number of the snapshot taken) This file stores the state of the virtual machine memory when the snapshot was taken.
• <machine name>-nnnnnn.vmdk (where nnnnnn is the number of the disk image, not corresponding to the snapshot number) These are log files which store changes to the virtual machine, since snapshot was taken. There may be many of these files over time.
