How to combine partitions in Windows Server and PC?
All disk partitions are allocated while installing Operating System, but you can change partition size without starting from scratch. Merge partition means combine two volumes into a larger one. It is useful when there are too many data volumes, which makes it difficult to identify the volumes. In other case, if a volume is running out of free space, you may merge another volume to occupy free space. In this article I’ll show you how to merge partitions with Windows built-in Disk Management and 3rd-party partition software. However, if you want to extend system C: drive by merging volume D, it is not a good idea, you’d better resize partition instead of merging.
Merge partitions in Windows Disk Management
In Windows 10/8/7/Vista and Server 2016/2012/2008 built-in Disk Management console, you can merge partitions indirectly. Why it is indirect? There is no merge volume there, but you can use Extend Volume function to achieve. If you are running Windows XP or Server 2003, there is no Extend Volume in Disk Management. To do this, you need 3rd-party software.
How to merge partitions in Disk Management:
1. Right click Windows flag on bottom left and select Disk Management.
2. For example to merge drive E: into D, right click drive E: and select Delete Volume.
Note: Remember to back up or transfer all files in drive E to other place before deleting.
Disk Management will pop up an alert to back up data, click Yes to confirm after backing up.
3. Disk space of drive E will be changed to Unallocated. Right click drive D and select Extend Volume.
4. Extend Volume Wizard will be launched, click Next to continue.
5. Click Next to use the default selected disk space.
6. Click Finish to confirm and proceed.
In a while, the Unallocated space is combined to volume D.
It is not difficult to merge partitions in Disk Management, but there are so many steps. It is much faster and easier to merge disk volumes with partition software.
Combine partitions with partition software
If you use Windows 10, 8, 7, Vista or XP (32 & 64 bit), you can merge drives with free partition software.
Step 2: Click the check-box in front of both drive D and E, and then select Merge selected volume to D.
Drive E will be merged into D, click Apply on top left to execute. (All operations work in virtual mode and physical partitions won’t be changed until you press Apply.)
As you see, only several clicks are required to merge disk drives. Open drive D in Windows Explorer, all files in drive E will be automatically moved to a fold in D which is named as E to D(with date time).
Resize volume instead of merging
As I said in the beginning, it is not a good idea to extend a drive by merging partitions. Instead, you can resize volumes, so you won’t lose any drive. It doesn’t matter to merge data volumes, but do not merge D to C, because all Windows services and programs in drive D stop working after deleting.

No matter you want to resize or merge partitions, you’d better select a safe partition tool, because there is risk of losing data when re-partitioning disk drive. Backup software is not enough especially for Windows servers, because it costs such a long time to restore and verify data if damage occur. The built-in Rollback technology of NIUBI Partition Editor can automatically roll back the computer to the status before these operations in ONE second, if any software error or hardware issue occur. It is very important to protect data and save time for both server and personal computer.
