As frequently using, disk available space become less and less, especially when you arranged many partitions in one disk, for instance, partition C or drive C is now 20G left, partition D, on the other hand 100G free space left, how to move this free space to system partition?

Windows disk management is the default disk manager build in by Microsoft, with basic functions like: extend volume, shrink volume, format, etc. if there is an unallocated space followed, you can click on it to do the extension job, however, most of the time, the extend volume bottom is grayed out, because there's no such unallocated space followed or exist. A new computer always set only one partition: system partition, the only one primary partition. How to solve the extend volume grayed out problem? This is what the extender does when the disk management tool cannot help.
Don't forget to "format quick" when you create a new one. Then "exit" to see the result, if there 's an contiguous unallocated space, you can use diskpart to extend partition/extend volume
