  • Number of storage hotplug devices: The number of hotplug storage devices that can be used in the session.
  • Private drive letter for storage drives: If this option is enabled, each hotplug storage device will be assigned an individual drive letter. If this option is disabled, a single drive letter will be generated for all hotplug storage devices and each hotplug storage device will be assigned a sub-directory.
  • Start storage drives with this drive letter: Letter that is assigned to the first hotplug storage device if automatic drive mapping is enabled. Further hotplug storage devices are assigned the next letter alphabetically.
