How to Extend C Drive in Windows Server 2019/2016

By default, the C drive on your Windows Server stores all system files, the operating system, apps, and any files you download from the internet. While it has a certain storage capacity, it can quickly run out of space if you save most of your data on it. The most common issue with the C drive is that it runs out of space. This is a prevalent problem in Windows Server 2019/2016. You can solve this issue by freeing up some space, but this is not a long-term solution.

If a disk runs out of space, it's preferable to extend the volume by resizing the partition. Otherwise, you'll continue to receive notifications that you're out of storage.

This article will explore how to extend the C drive on Windows Server 2019/2016. We'll cover using Disk Management and Server Manager to expand the drive, as well as recommend a third-party tool for a quick and error-free volume expansion. By the end of this guide, you should be able to determine the best approach to increase your C drive space. Let's dive in.

Yes, you can extend the C drive space in Windows Server 2019/2016. Here's a high-level overview of the process: 1. **Check Disk Space:** First, ensure that there is unallocated space available next to the C drive. You can check this using the Disk Management tool. 2. **Open Disk Management:** Press `Win + X` and choose 'Disk Management' from the menu, or right-click on the Start button and select it. 3. **Shrink Volume (Optional):** If there's no unallocated space, you may need to shrink an adjacent drive to create it. Right-click on the drive next to C: (usually D:), select 'Shrink Volume,' and follow the prompts to free up space. This will create unallocated space. 4. **Extend Volume:** Now, right-click on the C: drive and select 'Extend Volume.' A wizard will guide you through the process. Follow the steps to allocate the available unallocated space to the C drive. 5. **Confirm Changes:** Review the changes and click 'Finish' to apply them. Remember that you might need administrative privileges to perform these actions. Also, make sure to back up your data before making any significant disk modifications.

In Windows Server 2019/2016, you can resize a partition. Users of Windows Server would like to extend the partition because the C drive is almost out of storage space and needs more room to increase its capacity. Besides, it can also take advantage of unallocated space from other partitions, which helps organize data better.

The preferred way to avoid such issues is by allocating some space. You can extend the C drive by getting unallocated space from other volumes. If there's enough unallocated space in other volumes, you can assign that space. When your C drive runs out of space, it affects the overall performance of the system. Eventually, the system speed slows down, hampering your ability to perform tasks.
