Merge Partitions with Diskpart CMD

Using the built-in Diskpart tool in Windows, you can merge partitions through command-line operations. Follow these steps:

1. Open the Start menu, type diskpart.exe, and hit Enter.
2. In the Command Prompt, type list volume to display all partitions.
3. Select the partition you want to merge by typing select volume X (replace X with the volume label or number, e.g., select volume F).
4. Type delete volume to free up the space. This will make the volume unallocated.
5. Type extend to merge the unallocated space into the adjacent partition.

Note: This process will erase all data on the partition being deleted. If you want to preserve your data, consider using free partition software like IM-Magic Partition Resizer, which allows merging without data loss.

Merge Partitions Using Unallocated Space

If you have unallocated space on your drive, merging it with another partition is straightforward:

1. Follow the same steps above to open Diskpart and list volumes.
2. Select the target partition where you want to add the unallocated space using select volume X.
3. Type extend to combine the unallocated space with the selected partition.

Tip: Ensure the unallocated space is directly adjacent to the partition you want to extend. If not, tools like IM-Magic Partition Resizer can help rearrange partitions without data loss.

Merge Partitions Across Two Disks

Want to merge partitions from two different physical disks? Here’s what you need to know:

If the disks are configured in a RAID array (e.g., RAID 0 or RAID 1), they can be treated as a single logical drive. In such cases, follow the steps mentioned for Diskpart to merge partitions.

Steps:

1. Open Diskpart and type list volume.
2. Select the target volume using select volume X.
3. Delete the volume with delete volume to create unallocated space.
4. Extend another volume with extend.

Important: If your disks are not in a RAID setup, it’s not possible to merge partitions across them using Diskpart or any partitioning tool. Consider setting up a RAID array to combine two disks.

Merge Partitions with Free Disk Partition Software

For users unfamiliar with Diskpart or looking for an easier, data-safe method, IM-Magic Partition Resizer is a free tool that simplifies the process. Here’s how to use it:

1. Download, install, and launch IM-Magic Partition Resizer.
2. Right-click the partition you want to merge and select “Merge.”
3. Select the adjacent partition to merge into the first one. If the partitions are not adjacent, use the tool to create unallocated space and then merge.

Note: This software is 100% free for home users and supports advanced operations like redistributing unallocated space without data loss.
