create/shrink/extend/format partition. These features can help the users to
manage their partitions. Therefore, most users will choose the tool to extend C
drive directly. But the feature of Extend Volume is only available when there is
unallocated space adjacent to C drive. The limitation make you can’t expand your
partition freely.
