Unlike Move/Resize Partition which needs an adjacent unallocated to extend the target partition, Extend Partition allows users to extend partition by directly taking free space from other partitions or unallocated on the same disk.
Extend Partition with MiniTool Partition Wizard
1. Select and right click the target partition you want to extend, and then click “Extend” from the drop-down menu.
2. Select the source partition or unallocated you want to take free space from by clicking the pull-down menu.
3. Drag the handle leftwards or rightwards to a desirable extend to determine how much free space you want to take from the source partition or unallocated space. While dragging the handle, you can notice clearly that the new sizes of the target partition and sources are altering simultaneously. After that, click “OK“.
4. Click “Apply” to finish extending partition.
