1. Introduction

Partition merging is a means of combining two disk partitions into becoming a much larger one. People merge partitions for various reasons, the typical ones include decluttering and space-saving. When you buy a new PC, you'd likely find that the drive comes in a single partition.

But it could be the case that you're suddenly faced with a PC that is partitioned, perhaps you're a student who just purchased a pre-owned PC and can't deal with the complexity and chances for errors you'd be faced with when running a partitioned drive ( which could easily become unwieldy to manage). Some of these partitions are necessary to have, others are just needless and serve no useful purpose.

This article addresses how to merge two partitions on PCs running Windows 10.
