Cloning only used space means creating a copy of data from the used space on another disk space. This includes the computer's startup, settings, applications, etc. And are you looking for a way to clone only used space? Do you want to know how to safely clone used space without losing data? Don't worry. Here is a typical case study of cloning only used space:

I've installed a new 500 GB Samsung SSD 850 EVO. I want to clone only the "used" portion of my 2TB HDD (about 370 GB) to the SSD for faster performance when I boot, run programs, etc. when I go into "Disk Management," one option is to shrink the largest volume on my HDD. What issues do I need to watch out for?  - from Tenforums

Cloning only used spaces is a very common problem. And it is also not a difficult task. This article will help you with cloning-related issues. Before we describe the detailed cloning method, let's find out if you can clone only used space.

Can I Clone Only Used Space

Of course, you can clone only the space you use. Cloning only used space can save more cloning time. And it can create a data backup of the used space on the cloned HDD or SSD. In addition, cloning only uses space on the HDD to the SSD, which can also improve your computer's read and write performance. So, what tool should I use to clone?

As mentioned in the case above, you can't use Disk Management with Windows to do the cloning. What is Disk Management? Disk Management is a tool Windows provides for resizing partitions and creating or deleting them. However, it does not offer a cloning method. You need to use a professional cloning tool: EaseUS Partition Master, to complete cloning easily.

The tool supports disk cloning and partition cloning. And you can also edit the size of the partition you want to clone so that the partition is limited to the used space. Let's take a look at how this reliable tool works.

Before starting the cloning process, please use backup software to back up all necessary data on the target disk. This is because the cloning process will erase data from the target disk. Besides, you should ensure that the target disk has enough space to store the data on the used space of the source disk.
