This is how to Shrink a volume, split off a partition, delete volumes, and combine or extend volumes in Windows 10.
In this video tutorial I will be showing you how to first free up space to allocate to a new drive partition. Then I will walk you through formatting the free space to make it into a usable drive. After which I will show you how to delete the drive, delete the partition, and recombine the free space with one of the remaining drives (also called expanding a drive).
The Video Tutorial is at the bottom of this article!
Making Free Space & Creating a New Partition
We need to get into the disk manager. To do that open the file explorer, right click on “This PC”, and choose “Manage”.
In the computer management window go to “Storage” and click “Disk Management”.
From there choose which drive you would like to free up space on for the new drive. Here I will choose the D: drive. Click the drive to select it then right click and choose “Shrink Volume…”
From this screen we can enter the number of megabytes we want out new volume (drive) to be. I am going to take 50,000 MB which is 50 GB. After you have entered your desired amount click “Shrink”.
You will now see a black bar over a new section. This represents the unallocated disk space. Right click on it and choose “New Simple Volume…”
A wizard will open. There will be a few pages of options. I suggest just clicking next all the way through unless you are an advanced user. Upon hitting “finish” the new partition will be created and formatted. It will automatically open so you can see it in all its glory!
Deleting a Volume, Partition and Extending a Volume!
If you want to add all of a drive’s memory to an existing drive we need to delete the Volume. Right click on the drive and select “Delete Volume…”
That will make the volume unusable and turn its title bar a bright green, but the actual partition will remain intact. We need to right click the “Free Space” and select “Delete Partition…”
That will turn the partition back into unallocated space. Now another drive can be extended into that free space. To do that right click on the drive you want to add the space to and select “Extend Volume…”
Again a wizard will open and guide you through the process. I suggest clicking next and finish, unless you only want to add a portion of the unallocated space.
