After installing the Windows 10 April 2018 Update the OS started to warn me about low disk space on Disk M:. This partition (I have assigned a letter to it because I am curious) is where (I think) the recovery files of Win10 are kept.

Of course this logical disk has been created from the previous installations of Win10 and now I am afraid that a future update will fail if more space is required to host a recovery copy.

I would ask the community about which are my options here:

  • Forget it because the updates are smart enough to fix the problem?

  • Do we have some tools that could help me resize in a non destructive way the partition sizes?

  • Can I dig into this Recovery folder and cut away some excess and free more space?

Removing the assigned drive letter will stop these warnings.

They are only appearing because you gave the drive a letter and you really don't need to care what is on a 500MB partition on a 1TB disk.

In the same way you added a drive letter to it you can remove the drive letter. Just right click the drive in the disk management console, and in the "assign drive letter" dialog you simply remove the letter assigned to it. You don't need to care about what's on that drive, you are giving (some of the crappiest) malware access to critical system recovery files and quite frankly seeing that drive is a waste of a perfectly good drive letter.

Chances are that the data on that partition is minor, only used when doing a system restore and given the size of it is not even a full system image. It is probably just a couple of drivers that Windows will ignore as a latest copy will have newer versions.

The data on it probably "increased" because you gave it a drive letter and during installation of something Windows created a restore point and used the space.

You don't need to know what is on that disk, Windows probably will never use it again, and it's too small to care about recovering.

    I have followed your advice and removed the disk letter to that partition. The only problem was the Disk Management tool not allowing me to do anything on that drive but remove everything. I have followed the diskpart route as explained here https://social.technet.microsoft.com/Forums/office/en-US/1ba097f6-8a0b-43d8-a826-928458c4ba15/change-drive-letter-and-paths-greyed-out-cant-assign-drive-letter?forum=w7itprohardware – Steve May 01 '18 at 09:35
  • And I can confirm that no more warnings are displayed by the OS – Steve May 01 '18 at 18:40
  • I used diskpart as well. This answer lead me to remove the disk's letter, but I couldn't do it with the disk management tool. The link @Steve gave lead me to diskpart, but I had to find the right command: https://www.howtogeek.com/197296/how-to-use-the-diskpart-utility-to-assign-and-remove-drive-letters/ – dsnunez Jun 28 '18 at 01:01
  • You can try deleting temporary files and other junk files. Windows has a built-in Disk Cleanup tool that can help you delete temporary files, log files, and other junk files that are no longer needed. To use the Disk Cleanup tool, open File Explorer and navigate to the drive where Windows is installed (usually the C: drive). Right-click the drive and select Properties. Click the Disk Cleanup button and select the types of files you want to delete. If you still getting the same warning, check here https://www.easeus.com/partition-master/low-disk-space.html are some ways to fix this error – Nooruddin Lakhani Nov 21 '23 at 05:40

Removing a drive letter or just deleting something called the "Recovery Partition" does not seem like the reasonable answer. When you install Windows 10 as a fresh install on a clean or formatted hard drive, it creates four partitions. One of those is a Recovery Partition, and it is necessary.
What if you DO need to work from the recovery environment?
What if Microsoft issues a fix?
If the partition is hidden, renamed, deleted or otherwise, then how is the patch going to be able to be applied?
I have used diskpart but to no avail. to actually see what has been placed onto this partition.
