On the main screen, you can click the “Extend Partition Wizard” link on the left sidebar to start the wizard. It will show a new window asking if you want to extend the system partition (C:) or other hard drive partition. You can then follow the step-by-step guide to complete the partition extending process. The Disk/Partition copy is also one useful feature. It can create a complete clone of your existing disk/partition so you can restore to it in the event that your main hard disk crashes. You can choose to copy only the used space of the disk, or a full clone of the entire disk. Features such as resizing, creating new partition, moving, formating are also handy. There is even a check partition function where it can check the integrity of your disk. Wrapping up, disk partitioning is not something that you play with everyday, but when you need to do it, it is always handy to have such a tool around.
