A Better Way: Use Partition Master

While Diskpart is a useful built-in utility for managing partitions in Windows, there's a more user-friendly and feature-rich solution available: the Partition Master Professional. Unlike Diskpart, Partition Master Professional boasts an intuitive and straightforward interface. This means you can efficiently handle partition management even if you're not familiar with the complexities of command lines.

Notably, it features the “Resize and Move” function that allows users to extend partition with unallocated space that is not adjacent to the partition. This flexibility is an advantage over Diskpart, which requires unallocated space to be adjacent.

The steps to extend a partition using the Partition Master Professional tool are as follows: 1. Firstly, download and install AOMEI Partition Assistant Professional. Make sure the software is installed on your computer. 2. After installation, launch Partition Master Professional. You'll see a user-friendly interface displaying all hard disks and partition information on your computer. 3. On the main interface, locate the partition you want to expand. Typically, this would be Drive C or another drive where you need more space. 4. Select the partition you wish to extend, then click on "Extend Partition" or "Resize/Move Partition" from the right-side menu. The option may vary slightly depending on the version. 5. In the popup window, you'll see the current size of the partition and available space. Drag the slider on the right side of the partition bar to the right to increase its size. Note that you must have unallocated space adjacent to the partition to expand it. 6. Once you've confirmed the new partition size, click the "OK" button. Return to the main interface, and you'll see a list of pending operations. 7. Before making any changes, strongly recommend backing up important data as a precaution. After verification, click the "Execute Operation" or "Apply" button to start the partition expansion process. 8. Partition Master will begin executing the task, which may take some time depending on your hard disk size and system performance. Be patient and avoid closing the software or cutting power during this process. 9. Upon completion, the software will notify you. At this point, you can verify if the new partition size has successfully updated. Please note that these steps might vary slightly depending on the specific version of the software and the user interface. If you encounter any issues, refer to the Partition Master Professional help documentation or seek online support.
