When You Need to Merge 2 Unallocated Spaces in Windows
In one of the following 3 situations, users may want to merge 2 unallocated spaces into one:

Situation 1: there are 2 separate unallocated spaces on the same hard disk, and you want to combine them to one so as to create a larger partition.



Situation 2: a 3TB or larger hard disk is divided into 2 unallocated spaces, and you want to merge them together so as to use all space of the disk.



Situation 3: 2 small unallocated spaces are located on 2 different hard disks, and you hope to merge them to create a larger partition.

Well, how can we combine unallocated spaces in Windows 7, Windows 8/8.1, Windows 10, or Windows Server operating systems? See the following part to get detailed steps.

How to Merge 2 Unallocated Spaces to One in Windows7/8/8.1/10 and Server

• In situation 1, you can do like this:
Download and install MiniTool Partition Wizard, which is a free partitioning software for Windows home users. To operate on Server, please purchase the server edition. Then, launch it to get its main interface:



Here, please select one of partitions neighboring to unallocated space and choose "Move/Resize Partition" feature.



Then, drag the whole partition handle to change the position between unallocated space and the partition, and click "OK" to continue.



Use the same way to move partition position until 2 unallocated spaces are merged, and at last click "Apply" button to perform all changes.


• To merge 2 unallocated space into one in situation 2, please do like this:
Firstly, launch MiniTool Partition Wizard to get its main interface.

Then, select the disk which is divided into 2 unallocated spaces and choose "Convert MBR Disk to GPT Disk" feature from the left side.



Tip: on an MBR disk, we can only use 2TB (512B sector disk) or 16TB (4kn disk) of space while GPT disk can grow to a very large size.


At last, click "Apply" button to perform the change since 2 unallocated spaces has been combined to one.


• In situation 3, please follow steps below:

Firstly, convert both hard disks to dynamic disk via the right click function "Convert to Dynamic Disk".



Then, create a spanned volume which can use unallocated spaces on 2 different hard disks: right click one of unallocated space, choose New Spanned Volume feature, then click "Next", select and add unallocated space on another hard disk, click "Next", assign the new volume a letter, format the volume, click "Next", and finally click "Finish" to perform all changes.

Now all our ways to merge 2 unallocated space in Windows are shown, which are easy to be mastered, right? Just choose the most appropriate one by considering your actual situation, and we hope it useful.
