"How to merge partitions in Windows Server quickly and effectively? While merging two drives, do we lose data of both drives?"

While many files are flipped into your Server computer, you may find that one partition is filling up, but others are empty. Combining two partitions into a significant section is a hot trend, extending drive space and convenient partition management. Whatever your goals are, you may wonder how to merge partitions in Window Server without losing data. If you have the same questions, here are helpful solutions for combining two volumes into one. You can learn to merge adjacent or non-adjacent volumes via Disk Management and EaseUS Partition Master.

Secure Solutions to Merge Adjacent and Non-adjacent Partitions in Windows Server:

Workable Solutions Step-by-step Troubleshooting
Fix 1. Merge Adjacent Disk Partition in Windows Server 2012/2016

1. Use Disk Management: Run programs and right-click partition...Full steps

2. Run EaseUS Partition Master: Choose "Merge" feature...Full steps

Fix 2. Non-Adjacent Two Partitions in Windows Server 2012/2016 Allocate space from other drive to C drive with EaseUS Partition Master...Full steps

Merge Adjacent Disk Partition in Windows Server 2012/2016

Here are two options for merging partitions - Windows Server Disk Management and third-party software. Applying professional software is more uncomplicated than Windows built-in program; you can refer to Method 2 (Use merge feature directly.)

1 - Combine Disk Partitions with Disk Management
2 - Merge Two Partitions via EaseUS Partition Master

1 - Combine Disk Partitions with Disk Management

Restriction: Disk Management can only works to merge NTFS partition. Disk Management can only works to merge NTFS partition. 

Windows Server Disk Management can merge partitions instantly. But you can not find the "Merge Partitions" function directly. The only way to combine sections is to delete the adjacent volume first, then use unallocated space on by "Extend Volume" button. 

Use Built-in Tools to merge adjacent partitions without data:

Step 1. Right-click Windows Start icon and click Disk Management.

Step 2. Right-click the nearly empty partition and choose "Delete Volume ."Confirm Yes. (Read Notice first!)

Notice:
"Delete Volume" will erase all data on it. So, remember to back up all files before clicking Yes.

Step 3. Then right-click the entire drive select "Extend Volume..." to merge partitions.

choose the extend volume option

2 - Merge Two Partitions via EaseUS Partition Master

Available: Support merges NTFS or FAT32 partition. No data loss.

As mentioned above, you need to delete volume if running Disk Management while merging the partition. The "Delete" operation will cause data loss if your mouse goes too quickly to click Yes. A third-party disk manager, EaseUS Partition Master, can help you out to merge partitions in Windows Server. 

This software is compatible with Windows Server 2003-2019, Windows 11/10/8.1/8/7. It can easily merge two successive partitions without data loss. Moreover, this trusted software also creates, resizes, clones, creates, delete, and formats partitions.

If you want to merge non-adjacent partitions, EaseUS Partition Master and Disk Management can combine non-adjacent volume. The steps to use the built-in tool is the same as Method 1 - Delete targeted volume first, then choose "Extend Volume" to merge unallocated space to source partition.

Use Effective Way to Merge Partitions in Windows Server

In this post, we mentioned Disk Management and third-party software. Disk Management is a standard tool for managing volume, such as extending volume, formatting, deleting volume, changing the drive letter, etc. It needs to delete volumes first. Whether you want to merge adjacent or non-adjacent, EaseUS Partition Master will protect your data as usual.

Aside from the "Merge" function, you can free use this software's resize, extend, and shrink features to expand disk space or speed disk performance. The most important thing is that we support merging NTFS and FAT32 partitions.
