If you are starting a new system or you have not yet built any further partitions. You can find the C drive and other partitions in their default size. The partition drives are resized according to your preferences. It is not advisable to put all of your data in a single partition drive. For your data, files, and applications, you will need to create different partitions.

When data is kept in multiple partitions, it reduces the risk of data loss. Furthermore, when your C drive is full, the notification ''Low disc space" will appear. It also has an impact on the system's overall performance. Having many partitions allows for better data organizing.

This article will help you if you are running low disk space issues or resizing the partition. We will look at the detailed methods for resizing partitions to improve system efficiency. We will also recommend a tool that can execute the task flexibly. It protects your data and resizes partitions quickly. By the end of this article, you will be able to create and resize partitions So, let's get into the detail. 

Why do You Need to Resize Windows Server Partition? 

If you have a low running space problem or if your system requires partition resizing, you may be wondering why I need to resize the window server partition when the partitions already exist. 

Partitions are required for a variety of reasons. If you have a lot of data on a C drive and it is running out of space, it will eventually have an impact on the performance of your system. For the system to run error-free partition must be rightly allocated. 

Furthermore, if your system fails or is infected with a virus, the data stored on drives other than the C drive will be safe. Sometimes you have a lot of unallocated space in your system partition that is not in your use and remains vacant. You must assign it to make the most of the capacity in the available partition. 

Partitions are also helpful while transferring data when cloning or using an external drive. If your system is not working, you need to organize your data. You should also consider resizing the partition to correctly allocate the available space.

Run Disk Management to Extend/Shrink Server Partition 

Now we will look at how to create a partition on a drive. A disk management system creates partitions. This default feature is capable to create a partition. Disk management's only shortcoming is that it can only work if there is unallocated space behind your partition.

The steps to extend/shrink a server partition are as follows:

Step 1. Go to the Windows icon. Select Disk Management with a right-click.

Step 2. We will start by shrinking the basic disk. To shrink a partition, right-click the drive and select shrink volume. 

right click on disk and select shrink volume

Step 3. It will ask you to enter the volume in MB to shrink volume. Click on shrink. You will have your drive shrink.  

enter MB and select shrink

Step 4. After shrinking the volume you can see the unallocated space available in your drive.

Now we will look at Extending the disk volume.

Step 1. Select the drive you want to extend. Right-click and select extend volume.

Step 2. The Extend Volume Wizard will appear. Click on Next. 

Step 3. You will see the unallocated space on the hard drive. Enter the amount of MB and click Next.

enter MB and click on Next 

Step 4. Complete the procedure by clicking on Finish. You will have your partition size extended. 

Resize Server Partition with Diskpart 

The second method to resize the Server partition is with Diskpart. The steps are listed below: 

Step 1. Go to the search box. Type command prompt and click to run it. 

Step 2. Type diskpart and press enter. 

Step 3. Type command select disk 0 and press enter. Here you will type the name of the disk you have in your system.  

type command - 1

Step 4. Type list partition. It will show the number of partitions your system has. Here we have two partitions.  

type command - 2

Step 5. To select the partition that you want to extend. Type select partition 2. 

type command - 3

Step 6. Now to extend the size type command extend size=512 and press enter. You can specify the size as per the available system in your space.

type command - 4

Step 7. Now your drive is partitioned. Type exit to end the process. 

Do note that Diskpart would not resize if there is no unallocated partition behind your target partition. In addition, it cannot move the partition.
