This article introduces how to merge non adjacent partitions in Windows 10/8/7/Vista/XP (32/64 bit) and Windows Server 2019/2016/2012/2008/2003 R2.

How to combine partitions in Windows without software

All disk partitions are allocated when installing Operating System, but sometimes you need to merge two partitions. For example: C drive is running out of space, you may consider merging with another volume to increase free space. If there are too many volumes created, you may also combine partitions together.

To combine two partitions, one of the choices is running Windows native Disk Management. However, only when your disk partition configuration meet the requirements, yon can merge 2 partitions without software. For example: there are drives C, D, E and F in the same disk, if drive D and E are both Primary or Logical partition, you can combine drive E to D by following the steps:

  1. Back up or transfer all files in drive E.
  2. Press Windows and R on your keyboard, type diskmgmt.msc and press Enter to open Disk Management.
  3. Right click drive E: and select Delete Volume.
  4. Right click drive D: and select Extend Volume.
  5. Simply click Next till Finish in the pop-up Extend Volume Wizard window.

Shortages of Disk Management to combine partitions:

  1. In Disk Management of Windows XP and Server 2003, there is no Extend Volume feature, so you cannot merge partitions with it.
  2. If drive D is Primary but E is Logical, or drive D is Logical but E is Primary, you cannot merge partitions in Disk Management, because Extend Volume is grayed out for D after deleting E.
  3. Disk Management can only merge a partition to the left contiguous one, such as combine E to D or D to C. In addition, the left contiguous partition must be formatted with NTFS file system.
  4. Windows Disk Management cannot merge non contiguous partitions.

To combine contiguous partitions without these limitations, follow the steps in the video. This article introduces how to merge non adjacent partitions in Windows Server and PC.

How to merge non adjacent partitions in Windows PC & Server?

To merge non adjacent volumes in Windows computer, for example: combine C and E drive, or merge D and F drives, Disk Management cannot help you, because Extend Volume function can only combine Unallocated space to the contiguous partition on the left.

In this situation, you need 3rd party software to move partition. Among these software, NIUBI Partition Editor has unique 1 Second Rollback, Virtual Mode and Cancel-at-well technologies to protect system and data. Furthermore, it is much faster because of the advanced file-moving algorithm.

Steps to merge non adjacent partitions in Windows 10/8/7 and Server 2019/2016/2012/2008/2003:

  1. Download NIUBI Partition Editor, right click E: and select Delete Volume (remember transfer files in advance), then its disk space will be changed to Unallocated.
  2. Right click D: and select "Resize/Move Volume", drag the middle position towards right in the pop-up window, then Unallocated space will be moved to the left of D.
  3. Right click C: and select "Resize/Move Volume" again, drag the right border towards right in the pop-up window, then Unallocated space will be merged into C drive.
  4. Click Apply on top left to take effect. If you changed your mind, simply click Undo to cancel the pending operations.

Resize partition volume instead of merging

It is easy to merge two non adjacent partitions with NIUBI Partition Editor, however, you'll lose a partition after merging. If it isn't an issue, of course you can do like this. But, if you don't want to transfer files or don't want to delete this partition, you'd better resize partitions instead of merging.

For example: if you want to extend C drive, you may either shrink the adjacent drive D or the non-adjacent partition E to get Unallocated space, and then add Unallocated space to C drive. By this way, everything keeps the same with before except partition size. Watch the video how to do this:

Besides merging contiguous and non adjacent partitions, shrinking and extending partitions, NIUBI Partition Editor helps do many other disk partition management operations. To Windows 10/8/7/Vista/XP home computer users, there's free edition (100 clean without any bundles).
