Windows 10 version 1803 - low disk space drive "D" - other files

I'm getting a low disk space error for drive "D".

I've cleared out everything I can find, but the majority of the space is being used by a category "Other".  I've tried clicking and right clicking - but I can't get any additional information on what "Other" is.

When I open drive "D" from file explorer - there are no files or folders displayed.

Plenty of space on drive "C".

How can I fix the low disk space on drive "D"?

Hi JB. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.

There is an issue where Version 1803 adds a drive letter to the Recovery partition that should be hidden because it's only used for bootable repair tools that in previous edition of Windows were on C drive. Then it reports that it is full.

Since the partition is to meant to be hidden it can't have drive letter removed in Disk Mgmt like other partitions. So:

1. Select the Start button, type cmd and then right-click Command Prompt in the search results and select Run as administrator.

2. In the Administrator: Command Prompt window, type diskpart and press Enter.

3. Type list volume and press Enter.

4. Make note of the volume number for the drive letter you want to remove. For example, if the drive letter you want to remove is Drive “D”, note the volume number for Drive D.

5. Type the following command, and press Enter.

select volume <volume number>

When typing this command, in place of <volume number>, substitute the volume number you made note of in Step 4. In the example above, if the volume number for drive G is 5, you would type: select volume 5

6. Type the following command and press Enter.

remove letter=<drive letter>

When typing this command, in place of <drive letter>, substitute the drive letter you want to remove. In this example, you would type: remove letter=G

7. Close the Command Prompt window.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

Greg, thank you for posting the fix.  I have seen some computers, after three or four reboots, seem to correct the issue, because the D: drive is not listed in the File Explorer view any longer.  I'm glad to know that we can just use diskpart to remove the drive letter.  Is there a way for us to mark your answer as "the" answer?
