As a Windows user, you’re likely to run into the problem of running out of space on your C drive , but the D drive has a lot of free space. So is there a simple way to get that free storage?

Download a dedicated partition software such as EaseUS, then right-click on the D drive and choose the “Allocate Space” option. Select the C drive and drag the partition panel to the right side to add the allocated space from the D drive and press OK. Finally, click “Execute Operation” and apply.

How Do I Move Free Space From D to C Drive?

With reliable partition management software such as EaseUS, you can easily partition hard drives on both Windows 7, 8, 10 versions and optimize how you use your disk space. Partitions can also be resized, merged, moved, formatted, created, or deleted using the program. Here is how you can use a partition management tool to move space from D to C drive.

· Right-click on the D drive and use the Allocate Space feature to increase free space on the C drive from the D drive.

· Select the target partition, which in your case is the C drive, and drag the partition panel towards the right and confirm by clicking OK.

· Finally, select the Execute Operation option and press the “Apply” button to begin transferring free space from the D partition to the C disk.

How Do I Move Free Space To Another Partition?

If you want to move free space from one partition to another but on the same disk, you can easily d that in just a few steps. For instance, if you want to transfer the free space in the D drive to the C drive, you only need partition software to help you with that.

However, if the two partitions are on separate disks, you must first convert your basic disks into dynamics disks before moving the free space. Also, you require a dedicated partition manager tool before accomplishing the process.

Afterward, you can follow the steps below to move free space to another partition, even if they are different drives.

Convert Primary Disk Into Dynamic

Right-click on the disk you wish to manage and select the option that allows you to convert into dynamic form and confirm if the conversion is a success. Next, select the disk with free space and convert it into dynamic in the same way.

Merge The Two Disks Into One

First, ensure that the other dynamic is unallocated space. If not, it then forces you to delete all the partitions in the disk since you will not be able to merge the system partition.

Next, right-click on the entire disk and choose the Resize/Move option. From here, you can drag the partition panel leftward or rightward with your mouse, which helps to extend the partition size.

Finally, select the “Execute Operation,” thus enabling you to merge space from one disk to another.

Note: it is typical to find the unallocated space on the left side of the partition you wish to extend. As a result, in order to move free space, you should drag the left partition handle towards the left, depending on the size you want.

Can I Use Windows Tools Or Download A Program?

Since the PC generates junk files when running, it utilizes the space on the C drive, which affects the performance of your PC.

As a result, you may want to relocate free space from one drive to another in order to expand the system partition, especially if the secondary drive has a lot of free space.

Fortunately, there are many programs that you can use to transfer unallocated drives between drives. You can either use the built-in Windows Diskpart or install third-party software. However, Windows’ Disk Management software features several limitations which you must know beforehand to avoid later inconveniences.

Computers running on older Windows versions lack both extend and shrink features. Even worse, Diskpart does not support boot extensions and system partitions, denying users the ability to move space to system partitions.

On the other hand, installing an open-source disk partition software comes with numerous benefits that lack in Windows built-in partition tool.

You can use a third-party partition software to relocate empty space from the D drive to the system partition, making it a superior solution.

Not all computers come with a perfect partition. As a result, you may face several disk space issues, especially when running out of space in the C drive.

This results in a low-performance issue with your PC, which can be quite frustrating. So, consider repartitioning the hard drive, especially if you receive the Low Disk Space warning.
