Resize partition with Windows 7 Disk Management

Resize volume means change the size of existing disk partition, some people want to decrease partition size while other people want to increase partition size, so I have to divide into 2 parts.

Part 1 – how to shrink volume

  1. Press Windows and R on keyboard, type diskmgmt.msc to open Disk Management.
  2. Right click C drive and click Shrink Volume.
  3. Enter the amount of space to shrink and click Shrink to execute.

Note: in some situation you cannot shrink large amount of space, refer to the guide of shrinking Windows 7 volume.

Part 2 – how to extend volume

Note: only when there is adjacent Unallocated space on the right side, you can expand a drive with Extend Volume, otherwise, Extend Volume is grayed out, steps:

  1. Open Disk Management
  2. Right click the drive that has adjacent Unallocated space and select Extend Volume.
  3. Extend Volume Wizard will be opened, finish it.

It is very easy and fast to accomplish, but if you want to extend C drive by shrinking D, it is impossible, because the Unallocated space shrank from D is behind D, of course you cannot use it to expand C drive.
