How to Merge Partitions in Windows 7?

Merge partitions with Win7 snap-in Disk Management

Compared with Windows 2000/XP, Win7 built-in Disk Management contains two new functions "Shrink Volume" and "Extend Volume". With them, the two adjacent partitions can be merged in Windows 7. Here is an example of merging D drive to C.

Step1: Open Windows 7 Disk Management.

Step2: Delete D volume, don't forget to backup the data of it in advance. After deleting, D will become an unallocated space.

Step3: Right click on C and select "Extend Volume", and follow the extending instructions to increase C.

Tip: Win7 extending function is only available when there is an unallocated space behind the volume that we want to extend. If not, it is invalid.

The limitations of merging partitions with Windows7 Disk Management

  1. The two nonadjacent volumes can't be merged into one. For example, drive E cannot be merged to C if D is between them.
  2. The unallocated space can not be merged to C if it is not behind C.
  3. It takes a lot of time to backup data.

Based on the shortcomings above, it is necessary to find a professional and powerful partition manager to manage our hard disk drive. AOMEI Partition Assistant, as a magic partition software, is a good choice to computer users.
