I have a problem in snapshots manager as I dont see previous snapshots files except for "you are here" but there are 5 snapshot files in the vm folder. Can I just manually permanent delete those snapshot  EXAMPLE-000001 to 000006 files directly from folder? Since I can only see current state "you are here", I assume delete those snapshot won't cause any issue?

Current VM is working fine now but I need to clear up those space. Mine is VMware Workstation 14 Pro. Windows Server 2-12 for both Host and Guest.
