If you are looking for a way to extend a partition that is almost running out of storage space, well, you are in the right place. This article from EaseUS will present a detailed guide to teach you how to extend volume with Disk Management, which is a Windows built-in tool for managing disks and partitions. There will also be another preferable method. Now, continue reading and learn more.
As we just mentioned above, Disk Management is provided by Microsoft, which is a built-in utility to help Windows users manage their disks and partitions. You can use this tool to create volumes, initialize disks, extend and shrink volumes, etc. By managing your partitions and disks, you can optimize storage space and enhance the performance of your system.
Below are the steps with pictures for you to extend volume with Disk Management in 2 different cases.
- Disk Management can only extend a volume with adjacent free or unallocated space behind that volume.
Step 1. Press "Windows + R" to open the Run dialog box.
Step 2. Input diskmgmt.msc and hit "Enter".
Step 3. Right-click on your target partition and select "Extend Volume".
Step 4. Hit "Next" and then enter the size of the unallocated space to add to your target partition.
Step 5. Hit "Next" and "Finish" to complete.
#Case 2. There's no appropriate free or unallocated space on your drive, so you need to shrink a volume first.
Step 1. Press the "Windows + R" keys to open the Run dialog box.
Step 2. Input diskmgmt.msc and hit "Enter".
Step 3. Right-click your target partition and choose "Shrink Volume".
Step 4. Type in the amount of space you want to shrink for that partition and hit "Shrink".
It is worth mentioning that some users might find the "Extend Volume" option greyed out. This is mainly because there is no adjacent free or unallocated space behind the volume you want to extend, or the partition is a FAT or other format partition. You can read the following article for more details.
