Solutions to Merge Two partitions in Windows

Method 1: Merge Two Partitions via Windows Disk Management

When it comes to merging partitions, you may think of this tool – Disk Management. It’s a Window built-in utility for users to have some simple operations of disk management.

However, this utility doesn’t allow you to merge partition directly. Instead, you can achieve your goal by deleting the target partition and then recreate new partitions with the larger size.

Let’s have a look at the detailed steps of combining partitions in Windows.

As the shortcut shows in below if you intend to combine partition D and partition F, you need to delete partition F to increase free disk space, and then, use Extend Volume feature to merge the two partitions.

However, this way is not recommended as it will cause data loss when partition F keeps important data. This is what you don’t want to see. Is there any solution, with which you can merge two partitions without losing any data? OK, please move on to the following part to find the answer.
