Memory Snapshot

Hi,

Is there any impact, if I delete the memory snapshot (*.vmsn) manually (# rm -rf *.vmsn).

What will happen if I delete all (*.vmsn) manually and then try to delete the the 1st disk snapshot (.vmdk) that directly points to the basedisk using VSphere? (VM disk is thick Provisioning & host is esxi 4.1).

Thanks in advance
