Needs to be to edited for your environments and vcenter server names. This was written for an ESX 3.5 environment and I have not run it against vSphere. Some code liberated from the scripting communities at vmware.com.
#Script to report on orphan .vmx files
#Written by Josh Andrews 7/20/09
#
#Script assumes VIToolkit/PowerCLI environment
#Script assumes all hosts are in clusters
#Script assumes first host found in cluster will have access to all datastores
#Assumes if a cluster has one datastore that has already been searched then all
# its datastores have been searched
#Users running script needs adequate permissions to search
#dots function prints “.” accross the screen to give some feedback to user.
