Some switches are not available in all versions.
NTC is not used because Ghost enables the allocation of NTFS contiguous cluster runs by default. For instance, -NTC- forces Ghost to disable the allocation of NTFS contiguous cluster runs. Such switches are normally not used without the second hyphen. When a switch is both preceded by and followed by a hyphen, such as with -NTC-, the second hyphen means that the feature is disabled. This document lists Ghost's command-line switches in alphabetical order.
