If you have a partitioned hard disk and one of the partitions is running out of space, you can choose to merge partitions for larger drive space.And you can also choose to merge partitions for more free drive space under any other situations like:
"I installed windows 7 and I don't know what I did wrong, but this is what I end up with: C: 1.66 GB free of 9.44GB, where as I have total of 80 GB hard drive. And then I have drive "E" which has 64 GB free drive space. So how can I merge the partitions?" "I have partitions C and D. My problem is that C is smaller than D. How can I move some space to C from D or merge these partitions?" etc. No matter what is the reason, if you want to merge windows 7 partitions, you can achieve the goal by using EaseUS Partition Master.
For Windows 7, you can merge partitions with built-in Disk Management. But be noted that you need to delete the other partition first since Disk Management cannot resize the partition directly. While EaseUS Partition Master provides "Merge partition" feature to merge two neighbouring partitions directly. The comparison table below is about the main features between Windows 7 Disk Management and EaseUS Partition Master.
To ensure data security, EaseUS Partition Master also provides copy wizard to backup all the data in a safe place to avoid any unexpected data loss. Or you can choose free backup software to create image file to backup.
