Windows 10: Is it safe to delete a 885 MB partition right after C?

Hi, One of my friends wants to enlarge the C partition by deleting the D partition. The computer only has one HDD. But there exists an 885 MB hidden partition between C and D. What is it used for? Is it safe to delete?The language of the system is not English, and I added some necessary translations.The above picture is the result of Diskpart. Volume 6 marked with red underline is the partition we discussed. After assigning a letter G, I can check it in Explorer.It seems that no files in the window. But, there is some data in this partition.Is it safe to delete this 885 MB partition?&nb

Can I safely delete certain partitions?

All the partitions to the right of C:\ can be safely deleted. I noticed you have some substantial unallocated disk space that you should try recovering.

After deleting the suggested partitions, the Volumes you deleted will now appear as ‘Free space’, you will also notice that the disk icon no longer appears in the list of volumes.

Right click the Free space partition, and click Delete, click Yes on the Disk Management warning that appears.

The volume will now appear as Unallocated. Our next step is to merge back that unallocated free space with the system partition (C. Right click the System volume then click the ‘Extend Volume’ option on the contextual menu, click ‘Yes’ when the warning appears.

A wizard will now begin that will guide through the steps to merge back the unallocated space with your system partition.

The wizard provides a simple procedure to merge back the unallocated space with the system drive. Once you have selected the space, click Next, at the end of the wizard, you will see the amount allocated.

 

Resize partition C

In order to extend C and recover space from D, you will need to delete the 866 MB Healthy Recovery Partition and the Storage D:\ partitions.

There appears to be data on the D:\ partition.

I recommend you backup any important data on that partition before deleting it. After deleting the partitions, you will be able to extend C:\

Steps:

Right click the ‘Healthy (Recovery Paritition) and the
Storage (D’ partitions in Disk Management, on the contextual menu, click the ‘Delete Volume’ option. Click ‘Yes’ when the warning dialog appears.

The Volume you deleted will now appear as ‘Free space’, you will also notice that the disk icon no longer appears in the list of volumes.

Right click the Free space partition, and click Delete, click Yes on the Disk Management warning that appears.

The volume will now appear as Unallocated. Our next step is to merge back that unallocated free space with the system partition
(C. Right click the System volume then click the ‘Extend Volume’ option on the contextual menu, click ‘Yes’ when the warning appears.

A wizard will now begin that will guide through the steps to merge back the unallocated space with your system partition.
