Why need free disk partition magic for Windows 11/10/8/7?

A free disk partition magic usually contains many useful features including partition creation, partition extension, partition format, and so on. When you buy a new HDD or SSD, you need to initialize it first so that it becomes usable. But it's not enough since there's only unallocated space after the initialization. What you should do next is to create partitions from the unallocated space; or sometimes, you find your HDD or SSD is not properly partitioned, for example, one of the partitions is not big enough. In this case, many people will use Windows built-in disk partition magic - Disk Management - to extend the volume by combining the partition with a piece of unallocated space. 

What's the best free partition software?

As mentioned above, Disk Management is a reliable tool for disk partitioning in most cases. However, it's not the best one yet. Sometimes, people complain that when trying extending a partition, the option Extend Volume is greyed out. Why does this happen? Actually, to use Disk Management to enlarge a partition, the piece of unallocated space should meet 2 requirements - first, it should be adjacent to the target partition; second, it should be on the right side of it. So, if there're other partitions between the partition and the unallocated space, then, you cannot perform the volume extension.

Thus, here, I recommend another more powerful hard disk partition magic - AOMEI Partition Assistant Standard - to help you out. With this utility, you can move a partition and make it contiguous to unallocated space so that you can extend the volume with Disk Management. More than partition moving, other features including partition format, disk initialization, and partition creation are also available. 

What to do when the option "Extend Volume" is greyed out in Disk Management? Try the AOMEI freeware to resolve it flawlessly!

Alternative to Disk Management for partition extension

You may think it's a little bit time-consuming and complex to switch between Disk Management and a free disk partition magic in Windows when you want to extend a partition. To make everything much easier, AOMEI Partition Assistant Standard provides a more advanced feature - "Merge Partitions" - to help combine a partition with unallocated space regardless of their positions. 

1. Run AOMEI Partition Assistant Professional, right-click on the partition you want to extend and select "Merge Partitions".

Conclusion
