Is it possible to shrink volume and extend partition?

When do you need to shrink and extend partition server 2016? Situation when you have a large partition and want to create a new one or when there is not enough space on the volume to install programs or store files specially on C drive.The resize partition task-shrink or extend can be done using built in disk management tool.

Shrink/extend partition with built in disk management tool

In Disk management, select the volume that you want to shrink. Right click and select shrink. And then you can specify the amount of space to shrink and click on shrink. A new unallocated space will be created next to the volume. This unallocated space can be formatted to create a new drive.

With extend option, you can expand your existing drives. Resize your C drive is important if there is not enough space available on C drive . Extending your C drive or any drive from disk management tool is simple. Select the drive that you want to extend and select amount of space you want to extend. That’s it!

However, there are many limitations of disk management tool that does not allow you to resize-extend/shrink your drives. For example, the drive cannot be shrunk beyond the point where unmovable files are located. To create a new partition you have to format the drive and divide the space.

In the case of extending drive, you would not see extend option enabled. The reason is that to extend a drive, an unallocated space is required next to your target drive. Let’s say you want to extend your C drive, an unallocated space must be there behind your C drive. If it is not, then you cannot extend your C drive even after shrinking your D drive which is next to C drive. The unallocated space is created next to D drive. So in this case also, to extend your C drive, you are left with only format option. Formatting D drive creates an unallocated space. This is not recommended as you are loosing data from D drive.
