    This actually seems too good to be true.

    I assume C: can have a much of data on it or will that be lost in the process?
    Does this work only for dynamic disks?

    I have yet to find a free utility that allows me to merge partitions without data loss…hopefully this is it.

    Hi,

    You sure this works as diskpart cannot be used to expand a volume with the paging file on it or a system volume???
