Hi Vicky,
I could open the Datastore Browserr.
1 ) Should i power off the server when i move the folders to other storage?
2) There are three folders under root now. Should i move the folder "1. vSphere Management Assistant"?
1. vSphere Management Assistant
2. ISO (this is the iso which i used for install)
3. TESTMACHINE (the virtual machine name which i created)
Tank you.
