Disk expansion
First of all, confirm that the C disk and the expansion disk are on the same hard disk (disk), and the expansion disk must be adjacent to the right side of the C disk, with volume labels, such as C, D, E, F, etc.
Next, press Win +X at the same time, select Disk Management, and enter the Disk Management interface to view disks.
Second, be sure to back up all the computer data to the mobile hard disk or network disk outside the computer.
Third, uninstall the software installed on the expansion disk (such as disk D) in advance, otherwise it may lead to an error when installing again, and the software cannot be installed.
Fourth, begin to expand.
Step 1: Delete the partition on the right side of drive C and turn it into an unallocated partition.
1. Press win +X at the same time, select Disk Management, right-click drive D, and select Delete Volume.
2. If all the data of the computer has been backed up, click "Yes" to delete the D disk.
Step 2: unfold disk C.
1. Right-click drive C and select Extended Volume.
2. Click "Next" as prompted.
3. The system will automatically calculate the maximum expansion capacity. If there are no special expansion requirements, click Next and finish. You can manually enter the expansion capacity in the red box.
