Windows Server: Merge C Drive and D Drive by 3 Steps
Want to merge C drive and D drive in Windows Server 2019/2016/2012(R2)/2008 (R2)/2003 without losing data? Refer to this post to get detailed steps.
“I have a problem that my system partition with Windows Server 2012 installed is too small to install more software, while the D drive has a lot of free space that can be used to merge these two partitions together to increase the capacity of C drive?”
To merge C and D partition in Windows Server, you can try the following 2 methods. One is to make use of Server Disk Management while another one is applying a 3rd partition manager.
In Windows Server Disk Management, you cannot directly merge C drive and D drive since there is not such options like merge or combine partitions. The only solution is to delete partition D, making it an unallocated space, and then you can merge this unallocated space into C drive. At the same time, the D drive must be adjacent to the C drive on its right side.
Step 1. Press ”Windows + R” simultaneously, input “diskmgmt.msc” and click ”OK”.
Step 2. Right-click D drive, choose ”Delete Volume” and click ”Yes” to confirm.
Step 3. Right-click C drive and choose Extend Volume.
Step 4. Follow the prompts to complete the operation.
To combine C drive with D drive without deleting partition, you can turn to a third-party partition manager software for Windows Server: AOMEI Partition Assistant Server. It is compatible with Windows Server 2019/2016/2012 (R2)/2008(R2)/2003 and Windows 10/8.1/8/7, XP and Vista. After merging, you can see an enlarged C drive and a folder named D drive, which contains all data saved in the previous D drive.
Now, install and run AOMEI Partition Assistant Server on your machine and refer to steps on how it merges two partitions: C drive and D drive in Windows Server. You can download its demo version to have a try!
Step 1. In the main interface, right-click C drive and choose "Merge Partitions".
Step 2. Tick the tick adjacent partitions (merge unallocated partition is not in this limit) you want to operate. Here choose partition C and D. Click "OK" to continue.
Step 3. Then a preview of this operation comes out. To make it into effect, click "Apply" at the top-left corner.
So, it is possible to merge C drive and D drive in Windows Server 2008/2012/2016/2019. Two methods are available for your selection. In addition to merging two adjacent partitions or merging unallocated space into existing partition, the AOMEI Partition Assistant Server can also finish other challenging disk partition operations, such as recover deleted partitions, clone partition, move partition, clone hard disk, convert MBR and GPT without removing partitions and so on.
