How to get Unallocated space?
There are two ways to get unallocated space: delete volume and shrink volume. In all Windows Operating System, you can delete a volume by Diskpart cmd or Disk Management, the disk space of this volume will be changed to Unallocated. In Windows 10 Disk Management, you can also get unallocated space with Shrink Volume function. It is very useful if you forget to edit disk partition when installing Windows 10, so you can shrink C drive to release Unallocated space to create new volumes easily.
