Way 1: Increase Disk Partition Through Extend Partition

You can extend partition on Windows 10 by using the Extend Partition feature. This feature directly takes free space from any other existing partitions or unallocated space to enlarge a partition on the same disk.

Step 1: Launch MiniTool Partition Wizard to its main interface. Then right-click the partition to be extended and select Extend.

Step 2: Click the down arrow from “Take Free Space From” and select the partition to get expansion space. You can drag the sliding handle to decide how much of the available space it takes up.  Then click OK to return to the main interface.

Step 3: You can see that the partition has been enlarged, but it has not been applied to the computer yet, so you need to click the Apply button to perform all changes.

Way 2: Increase Disk Partition Through Resize Partition

If the target partition has unallocated space adjacent to it (left and right), you can use Move/Resize to extend disk partition Windows 10.

Step 1: Launch MiniTool Partition Wizard and go to the main interface. Right-click the partition to be extended and select Move/Resize to increase the disk partition size.

Step 2: Then in the popup window, move the arrow to the right to occupy the unallocated space. “Using Enhanced Data Protecting Mode” is checked by default here, which protects your data in the event of a sudden power outage. Then select OK.

Step 3: Finally, click Apply and the disk partition expansion will be completed.

Way 3: Increase Disk Partition Through Merge Partition

To increase disk partition, you can try merging two partitions. The Merge Partition feature of MiniTool Partition Wizard can help you do that.

When using this function, you need to pay attention to two things: only partitions adjacent to the target partition can be merged; the other thing is that this function only applies to NTFS partitions. If the target partition is formatted with the FAT/FAT16/FAT32 file system, please use the Convert FAT to NTFS feature first.

Step 1: Launch MiniTool Partition Wizard and go to the main interface.

Step 2: Right-click the source partition, and select Merge.

Step 3: In the Merge Partition interface, you can find the software has specified the selected partition to be expanded already. So, you only need to click Next to continue.

Step 4: Select the partitions that will be included in the previously selected partitions and click Finish. It is worth noting that the selected partition needs to be in NTFS file system format.

Step 5: You can preview whether the partition will become larger, then click Apply to save the changes.
