No matter which case mentioned above you belong to, a free partition manager – MiniTool Partition Wizard can help you out. Well, if you do not want to rely on a third-party tool, Windows built-in Disk Management can be your assistant to some extent. Only you have to know Disk Management sometimes has some limitations.

Now follow the steps below to get what you want:

Step 1: Open this tool and launch to its main interface by click Launch Application. Then you can see the disk map here.

Step 2: Select the partition you want to extend, and then choose Extend Partition. There are three places to click the feature. You can choose one to start extending:

Click Partition from the upper menu bar, then choose Extend from the drop-down list, or click Extend Partition from the left action panel. Or you can click Extend from the pop-up menu after right-clicking on the wanted partition.

Extend Disk Volume with Disk Management.

Windows built-in Disk Management also can extend the size of partitions. Let’s see how it works – taking Windows 10 as an example.

Step 2: Choose the desired partition and right-click on it. Then choose Extend Volume from the pop-up menu.

Step 3: Click Next on the jump-out window and then you will enter an interface to choose how much space you want to extend. You can keep it by default which means it will extend the partition to the entire unallocated space. Alternatively, you can set the value manually too.

Step 4: Click Finish to confirm the change.

Then you are back to the main interface in which you can see the target partition is extended successfully.

But in this step, you may encounter the feature Extend Volume grayed out that happens due to the limitations of Disk Management.

Why you can’t extend partitions in Disk Management? Because Disk Management asks for conditions as following:

1. If you are trying to extend a primary partition, there has to be an unallocated space right behind it.

2. If you are trying to extend a logical partition, there must be a free space right behind it.

3. Any partition you try to extend has to be a Raw or NTFS partition.

As you can see, both of these two tools can help you to increase disk partition in your disk, but they have a big difference. MiniTool Partition Wizard is definitely a better choice than Disk Management.

Without the above limitations, you can use this software to easily extend partition no matter if there is unallocated/free space right behind the target one.

Bottom Line
