How to increase partition size on Windows Server 2016

The same with previous Windows client and server platform, hard disk drives run out of space on Windows Server 2016, too. Luckily, if there is free space in any other drive, you can increase partition space without reinstalling OS or restoring. If there is no free space in all partitions, you can clone to a larger disk and increase partition size with extra disk space. This article shows how to increase disk space and partition size on Windows Server 2016 step by step.

Increase partition size by merging another drive

When change partition size on Server 2016, parameters of all related disk, partitions and files should be modified absolutely correct. Any error could cause disaster, so there is system and data damage risk if you use unreliable partitioning tool. Better than other disk partition software, NIUBI Partition Editor provides 1 Second Rollback, Virtual Mode, Cancel-at-will technology to ensure system and data intact. Furthermore, its advanced file-moving algorithm and Hot-Resize technology are very helpful to partition resizing.

Besides backing up, a good utility is very important to accomplish this task, otherwise, it costs a long time to restore if disaster occur.

For data drives, you can increase partition size by merging another drive by several clicks, steps:

Step 1 Download NIUBI Partition Editor, right click drive D or E and select Merge Volume.

Merge Volume

Step 2 Click the checkbox in front of both drive D: and E:, and then click the drop-down box on bottom to select destination drive. If you select D:, partition E will be merged into D.

Step 3 Click OK and back to the main window, there is a pending operation “Merge volume E: to D:” added on bottom left. Click “Apply” on top left to execute. All files in drive E will be automatically moved to a new folder in drive D named as “E to D (date and time)”.

Partitions merged

Tip By merging volumes, original drive E will be removed, although files are moved automatically. If you do not want to lose any drive, you can increase size of a partition by shrinking another one. Files keep intact and part of unused space will be transferred.

Increase partition space by shrinking other drive

In most of the servers, C drive is getting full and there is plenty of unused space in the adjacent drive D, so here I’ll show you how to increase partition size of C drive by shrinking D.

NIUBI Partition Editor

Step 1 Right click drive D and select “Resize/Move Volume“, drag the left border rightwards in the pop-up window to shrink it.

Shrink D

20GB Unallocated space is produced on its left side. (If you drag the right border leftwards, Unallocated will be produced on the right side.)

Drive D resized

Step 2 Right click drive C and select “Resize/Move Volume” again. Drag the right border rightwards to hold the Unallocated space.

Extend C drive

Click OK, C drive size is increased to 50GB, click Apply on top left to execute, done.

Increase disk space by cloning

If the entire disk is small, C drive is running out of space faster and you can get little free space from D drive. In this situation, you can clone this hard disk to another one. The extra disk space can be used to increase either or both drives, steps:

Step 1 Click “Clone Disk Wizard” under Tools on top left.

Run disk clone

Step 2 Select the source disk and click Next

Select source disk

Select the target disk and click Next.

Target disk

Step 3 Edit partition size and location. The extra disk space is displayed on the end of disk.

Edit disk partition

Click drive D on the disk map on top and then drag either border of D below, you can increase its partition size. Drag the middle position, you can move it. It is similar to increase C drive space, but you need to edit D first.

Edit disk partition

Step 4 Click Next and back to the main window, as you see, both drive C and D are increased, press Apply on top left to execute.

Partition size increased

In Summary

To increase partition size on Windows Server 2016, the first step is backing up and running the safe partitioning software such as NIUBI Partition Editor. When there is free space in other drive, you can increase partition size by merging or shrinking this drive. (To increase C drive size, you’d better shrink D).

If there is not plenty of free space in all other partitions, you can clone the disk to a larger one, and then the extra disk space can be used to extend any partitions one by one.
