Low disk space on recovery partition

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?

Solution 1:

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.
