Merge Partitions with Qiling Disk Master

Merging partitions can combine unused space and reduce the number of drive letters on a Windows disk. It is commonly used when the C: drive is short of space or when two adjacent data partitions should become one. Before merging, check the disk layout and back up important files.

Before merging partitions

• Back up files from both partitions, especially the partition that will be merged into another one.
• Do not merge EFI, Recovery, MSR, or OEM partitions into a data partition.
• Confirm that the two partitions are on the same disk.
• Close running programs that may be using files on either partition.

Step 1. Open Qiling Disk Master and locate the disk that contains the partitions you want to combine.

Step 2. Right-click the partition that will receive the space and choose Merge Partitions.

Step 3. Select the adjacent partition or unallocated space that should be merged. Read the note about how files will be kept.

Step 4. Confirm the target partition, drive letter, and final size in the preview window.

Step 5. Click Proceed and wait until the operation finishes. Do not power off the computer during the merge.

When merging is not the best choice

If the partitions are not adjacent, if the second partition contains a separate operating system, or if the disk has recovery partitions between them, extending or moving partitions may be safer. For a system drive, check boot and recovery partitions before changing the layout.

Conclusion

Qiling Disk Master can merge partitions with a preview-based workflow. The important part is to select the correct disk, avoid system-reserved partitions, and keep a backup before applying the operation.
