About "Merge Partitions"

Merge Partitions means to combine two or more partitions together. It’s another kind of way to extend a partition size. In fact, it comes with two cases: One is to merge two adjacent partitions into one partition; the other is to merge unallocated space into a partition. Anyway, the specific instructions will be mentioned later.

Although Windows built-in Disk Management has the function “Extend Volume”, there are many limitations. For example, if you want to extend a partition with an unallocated space, the unallocated space must locate adjacent to that partition and only on the right side. Moreover, If you want to merge partitions, you should delete the other partition before since Disk Management can’t directly resize the partition. Fortunately, freeware AOMEI Partition Assistant avoids such troubles. The following instructions will show you how to merge partitions in Windows 7 with this software. It supports Windows 8/8.1/10, too.
