How to shrink Windows Partition with ease

You may often use the function "Shrink Volume" of Windows built-in disk management tool, which could help resize partition and is very practical. But the built-in utility has a defect that it does not allow shrinking partition from the forward to the backward.

Hard drive shrinking is the practice of reducing the size of your partition to create unallocated space that you can use elsewhere. Before your computer can use the space on the hard drive to store data, the drive needs to be split up into separate areas, called partitions.

Each partition is distinct, almost like its own drive. Shrinking your hard drive happens when you shrink a partition -- the hard drive itself doesn't shrink, though.

We often use the function "Shrink Volume" of Windows built-in disk management tool, which could help us resize partition and is very practical. But the built-in utility has a defect that it does not allow shrinking partition from the forward to the backward.

For user's in-depth understanding, we'll demonstrate how to free shrink Windows partition with the built-in disk management tool.
Firstly, click "Computer – Manage – Disk management" to enter the following interface.


In this interface, select the partition to be shrunk (here, Partition G: is selected) and right click mouse. In the menu popping up, select "Shrink Volume" to go on.


In this interface, set the amount of space to shrink (20GB for example). After that, click "Shrink" and the system will shrink Partition G: from the backward to the forward by default.

The result is as follows.


After the shrinking, the amount of Partition G: changes from 100 GB to 80 GB and there is an unallocated space of 20GB behind Partition G:.

In the above demonstration, the shrunk unallocated space only can be used to extend Partition G: or create new partition instead of extending other partitions, so it shows that there is a great limitation of the system's built-in disk management tool in shrinking Windows partition.

Free shrink Windows partition with MiniTool Partition Wizard
Despite of the limitation of the built-in disk utility, we can use another more flexible method to free shrink Windows partition, namely taking advantage of the free partition magic MiniTool Partition Wizard.
Please visit to download this free partition magic and install it to the computer. Then launch it.


In the main interface, we can see the distribution condition of disk and partition in the computer. Select Partition G: likewise and then click "Move/Resize" to start shrinking Partition G:.


In this interface, drag the left triangle rightward or drag the right triangle leftward to free shrink Windows partition (here, we perform the former operation), just as follows.


Click "OK" after the shrinking, to go back to the main interface.


In the main interface, Partition G: changes from 100GB to 80 GB and an unallocated space appears in front of Partition G:. But this is only a preview effect, and we need to click "Apply" to perform the above operations, finishing shrinking partition in a real sense.

Check partition state via the built-in disk management tool and it shows a different effect.


Through comparing the two methods for shrinking Windows partition, we can see the second one is more flexible.
