Why Low Disk Space alert on Windows Server 2016 occurs?
“Hi, my Windows Server 2016 is displaying an alert for disk space usage. The alert is for the C drive - it has been slowing down my computer performance gradually. So, what should I do to solve this low disk space alert in Windows Server 2016 so as to restore the computer speed? Thanks!”
The low disk space warning is a prompt to inform users that a specific drive is running out of space and needs to be improved urgently. It is more likely to occur on the system (C:) drive since the Windows OS is installed in this partition, besides, the related Windows updates and some third-party programs intend to install there by default. In most cases, when the free space of one partition is lower than 10% of the total storage space, this low disk space error message will keep popping out frequently, or you might find that partition is with a red bar in File Explorer.
Solve “Low Disk Space” warning in Windows Server 2016 or 2019
When the “Low Disk Space” warning message pops out, you will have very little room available on your drive for the OS or software to work correctly. So, it is necessary to learn how to fix this issue. The most common method is to free up some storage space, which includes performing Disk Cleanup, delete unnecessary files or move them to another drive, save new personal files to another drive, run antivirus software, install the latest Server update, move apps to another drive and more.
Releasing some drive space absolutely can help solve the low disk space alert in Windows Server 2022, 2019, 2016, 2012 (R2), or 2008 (R2), but some users reported the released disk space will be full sooner or later. So, we would like to share a better and more effective way to tackle the “Low Disk Space” warning in Windows Server. That is to extend the partition that has a little space available. To extend a partition more conveniently in Windows Server, you had better apply a professional Server partition manager since the Windows Server Disk Management can only extend an NTFS partition that is followed by a contiguous unallocated space.
Then the AOMEI Partition Assistant Server is a great choice. It can directly transfer some free space from one partition to another partition, easily extending system drive or other data drives in all Windows Server and PCs. Only 3 clicks can make it done. You can download the demo version and have a free trial.
Step 1. Install and launch AOMEI Partition Assistant Server. Right-click a partition that has enough unused space and select “Allocate Free Space”.
Step 2. Here, you can set the free space amount you want to transfer to the partition that suffers “Low Disk Space” alert (ex: C drive) and choose the destination partition. Click “OK”.
Step 3. Click “Apply” and “Proceed” to commit the pending operation.
After the process is finished, the destination partition is extended with free space from another partition. In addition, if there are already some unallocated space on the disk, you can also use the “Merge Partitions” function to merge the unallocated space into the target drive successfully.
Summary
So, to fix “Low Disk Space” alert in Windows Server 2016 or 2019, you can either free up some storage space or extend the existing partition space. Choose a proper solution according to your requirements. Besides, you can also clone the Windows Server 2016 disk to a larger disk, or a faster SSD for an upgrade via AOMEI Partition Assistant Server software.
