Cleaning out an old datastore so I can reclaim the SAN space, I've migrated all VMs and templates off the datastore (and deleted the empty folders the migration leaves behind. Grrr...). There are two empty folders left on this datastore, labeled "clones" and 'masters". No one here knows how they got there, but they look kind of system-like. Anyone know if they are system folders that can be moved or can be deleted? (Screen shot attached)
