Manfred Meier a Web- and System-Administrator from Switzerland has written the ESX Console Manger utility that can do the following. List Virtual Machines and Virtual Disk information with the location and size of the files and directories (also for unregistered Virtual Machines). Rename Virtual Disks of registered Virtual Machines. Kill Virtual Machine Process (if the VM can't be powered off). List All Virtual Disk Flatfiles on a Datastore with size and modification date. And view Logfiles on the ESX Host. He also publishes lots of other VMware tips and tricks on his website ESXGuide.
