About Dell ExtPart
Dell ExtPart is a disk partition management utility. It supports old version of
Windows like Windows 2000, which does not come with Disk Management or DiskPart.exe,
so users running old Windows system like to use ExPart to extend or shrink partitions online,
which means you can extend system partition without shutting down your computer.
However, it is not perfect. When you try to expand C: drive using extpart.exe you
get the error Dell Extpart unable to connect to C or it doesn't exist. Is there
a way to fix this without cause downtime?

If, however, you are not satisfied with this workaround, you can use another free partition manager software to help
you to expand any partitions.
