1. Due to the insufficient space of your C drive, you will always get "low disk space" warning when you open your computer. Besides, the low disk space has direct effect on your computer performance.

2. At the beginning, you allocate enough space to C drive, however, day after day the partition mode is unbalanced and you realize there isn't enough space on your C drive. However, you find there is free space in other partitions. You image if you can extend C drive with those free space, the problem will be solved. What would you do?

To generate free space, some users will uninstall unnecessary applications and delete useless files. But after a couple of weeks, the same problems will appear again. Generally speaking, the direct way to solve the aforementioned issue is to extend system partition.

Disk Management is a built-in tool in Windows which can help you extend/format/delete/shrink/create partitions and change drive letters. Extending partition with Disk Management, you must have unallocated space next to the partition which you need to expand. Otherwise, the button is grayed out because you can only extend partition to adjacent space in Disk Management.

In the following window, you can see there is unallocated space behind D drive, but if you want to extend C drive by right-click, the Extend Volume is grayed out.
