Create a New Partition or Volume
Let us as an example say that you want to create a new volume or partition. So to do this, first select ‘Shrink Volume’.
Then, wait for some time while Windows check the amount of space available for Shrink. Enter the amount of space to shrink in MB and hit ‘Shrink’. Once you hit the button, you will observe some free space created. Check out the screenshot below.
Now, right-click on the free-space created and choose the first option ‘New Simple Volume’.
Then, select the amount of space you would like to allocate to the free space and click ‘Next’.
Now, assign a drive letter to your partition and move to the next step by clicking ‘Next’.
If you would like to store data on this partition, you will have to partition it first. So, format the partition with NTFS.
After the formatting process has been completed successfully, you can see a new partition created in your Windows Explorer.
Using this inbuilt Disk Management Tool in Windows 10/8/7, you can similarly create a partition, extend a partition, shrink a partition and do more very easily. See this post if your Extend Volume option is grayed out.
