What to do if the extended volume on the C drive cannot be clicked

The reason why the c drive extended volume cannot be clicked is because there is no unallocated disk partition on the right side of the adjacent partition of the C drive, so the c drive partition extension is gray and cannot be clicked; the solution: 1. In " In the Run dialog box, enter the "diskmgmt.msc" operation command; 2. Delete the adjacent partition next to the C drive; 3. Right-click the C drive and select "Expand Volume" in the pop-up shortcut menu; 4. Set the volume that needs to be expanded Partition size, click the "Finish" button.

#The operating environment of this tutorial: Windows 10 system, Dell G3 computer.

What should I do if I can’t click on the extended volume of the c drive?

Because there is no unallocated disk partition on the right side of the adjacent partition of the C drive, the C drive partition expansion is gray and cannot be clicked.

In the disk management, I accidentally found that the option to extend the volume of the c drive is grayed out and cannot perform expansion-related operations?

Cause analysis:

In Windows, the principle of expanding disk partition is:

Extended volumes can only use compressed volumes compressed from the adjacent right disk, ensure that the right side Adjacent disk partitions are unallocated so that disk space can be expanded.

In practice, some users’ computers have no unallocated disk partitions on the right side of the adjacent partition on the C drive. This causes the C drive partition expansion to be gray and the disk space cannot be expanded.

From the perspective of the operating principle, to solve the problem that the partition expansion of the C drive is gray;

The operation method is: delete the disk partition on the adjacent right side of the C drive to make it unallocated disk partition, and then expand the C drive space;

The specific operation process is as follows.

(1) Press the "Windows R" key combination and enter the "diskmgmt.msc" operation command in the pop-up "Run" dialog box.

(2) Delete the adjacent partition next to the C drive

(3) Right-click the C drive and select "Extend Volume" in the pop-up shortcut menu.

(4) The user follows the operation prompts of the Expand Volume Wizard to set the size of the partition to be expanded. After the setting is completed, click the "Finish" button.

This operation method seems relatively simple, but it involves deleting disk partitions. For users who do not understand computers, it is likely that disk data will be lost due to human error.

Therefore, novice users are not recommended to use this method to expand the C drive partition.
