Shrink dynamic volumes including simple volume, mirrored volume, striped volume, spanned volume and RAID 5 volume to release unallocated space which can be used to create new volumes or occupied by other volumes to make themselves expanded.

Extend dynamic volumes including simple volume, mirrored volume, spanned volume, striped volume, or RAID 5 volume to unallocated space to make the volume bigger.

Move a volume to adjust its position to meet your actual needs. (this operation also asks for unallocated space)

  • On dynamic disk, you can extend a volume by taking up unallocated space in another dynamic disk, and this volume will automatically convert to a spanned volume. But volume C is an exception. Windows doesn’t allow it to take space from other dynamic disks. While if there is enough unallocated space on the same disk to expand the target volume, it is still a simple volume after expansion.
  • What about extending a striped or mirrored volume? Firstly, there should have unallocated space on both dynamic disks, then, you can only use the same space on both disks to extend the volume. (The extended space cannot exceed of the smaller unallocated space)
