Why Merge Partitions Windows 7

Windows 7 users, actually more and more Windows 10 users are involved nowadays, once feel it necessary to extend a disk volume in order to hold more data, games, or programs. Some choose to directly resize a partition, while some choose to combine two partitions into a large one. Do you know in what circumstances people want to merge partitions? The following are some examples.

  • The system C drive is running out of space. As a result, the computer becomes extremely slow, or the system starts freezing a lot.
  • Too many hard drive partitions are scattered on a disk, making it difficult to locate files or make full use of every bit of hard drive space.
  • There is unallocated space on the disk. It's helpful to add unallocated space to some partitions.

The displayed examples all refer to one problem: improper disk space distribution. Therefore, to utilize disk space carefully and efficiently, it's a good idea to merge partitions in Windows 7, 8 or 10. By combining two hard drive partitions into one can help create a new volume with sufficient free space, to minimize the hard drive numbers, as well as to solve the problem of low disk space warnings.

In general, there are two typical ways to merge partitions in Windows 7. One is the built-in Windows Disk Management and the other is third-party partition manager software

How to Merge Partitions Windows 7 in Windows Disk Management

Windows 7 Disk Management doesn't provide the "Merge Volume" feature directly, but you can merge partitions by deleting a partition and then extending the other with unallocated space.

Requirements of Windows Disk Management for merging partitions:

  • The two partitions must be adjacent.
  • Both partitions should be formatted with NTFS 
  • You must delete a volume in order to extend the other

Combine two partitions in Disk Management:

Step 1. Right-click My Computer > Manage > Disk Management.

Step 2. Right-click drive D and select "Delete Volume". Drive C will be converted to unallocated space.

Step 3. Right-click drive C and select "Extend Volume". Follow the Extend Volume Wizard to add unallocated space to drive C.

Step 4. Return to the Windows 7 Disk Management interface, you'll see drive C and D being a new bigger drive C. 

You've successfully merge drive C and D into one partition by following the above instruction. However, there are still many restrictions that may prevent you from merging partitions. If you meet the problem that cannot extend volume or Extend Volume greyed out in Windows 7, fix it with the online tutorials. After troubleshooting, If you still can't merge partitions, or if you don't want to risk any data loss caused by deleting all partitions, you can use a professional partition manager to merge partitions more easily and safely.
