How to Shrink Volume Partition in Windows

There are times where you will want to shrink the amount of allocated space on your hard drive, referred to as a volume, to make room for another partition. Example if you need multiple partitions for your business data, you may need to remove or shrink the existing structure or if there is only a C drive on your PC, you can create several new partitions from C drive. Shrinking existing drives or volumes by using in-built shrinking feature through Disk Management, you can create a new drive or volume to place your important data or information separately. Now, we will walk you through how to create new partition from C drive in Windows 10 without formatting . Shrinking a volume is extremely simple and takes only a few minutes. Just follow these few steps.

Shrink partition a basic volume using the Windows Disk Management in Windows 10, 8 and 7

Press the Windows key + R to open the Run box. Type diskmgmt.msc and hit Enter.



Important!: The “Shrink Volume” option can only produce unallocated space on the right side of the shrunken partition. When you shrink a partition, the Unallocated space can only be created behind it. The Unallocated space shrank from a partition can only be used to create new partitions, it cannot be used to extend another one.

Now right-click on the volume you want to shrink and choose “Shrink Volume”. (See screenshot below)

Note: (F letter ) Normally this is the C drive. (that is  the directory where Windows is installed.)

For example: If you want to shrink 100 GB, then choose 100000 MB in “Enter the amount of space to shrink in MB”. You can only shrink a partition – volume if it has enough free space. if the partition you want to shrink is full of data, you cannot make it smaller as there is no space left on it to take away. In this case, the “Shrink” option is greyed out.
