Part 2. The Two Partitions are Not on the Same Disk

When you are trying to store a large amount of data on your computer or laptop, you may find the partition space is not enough for you. However, there are lots of free space on other partitions, so you may wonder if it is possible to transfer one partition's free space to another so as to enlarge the partition space in Windows 10/8/7. 
For example, transfer free space to C drive, or transfer free space on F drive (on disk 1) to C drive (on disk 0). We indeed could help! Follow the two parts below to move free space from one partition to another now.

Part 1. The Two Partitions are on the Same Disk

If the two partitions are on the same disk, it would be a piece of cake to transfer free space to another partition. For example, if you want to transfer D drive's free space to C drive, or move any partition's free space to another drive, you can follow these simple steps to realize it.

To transfer or move free space to another partition is pretty easy if you have a free partition tool. EaseUS Partition Master Free provides a feature named "Resize/Move partition" can help us transfer free disk space from one drive to another directly, for example, move free space from D to C drive in clicks

Tip
You can only allocate the unallocated space from one partition to another. If you don't have unallocated space, resize partition first.
EaseUS partition software has the most welcoming and versatile hard disk partition management features on MBR and GPT disk.

Then, you can follow the steps below to extend one partition.

 

Step 1: Launch EaseUS Partition Master

Run partition manager software

Step 2: Free up space to extend partition

If the hard drive has enough unallocated space to extend the target partition, jump to Step 3 and continue.

If not, free up space first:
1. Right-click on a partition next to the target partition and select "Resize/Move".
2. Drag the partition ends to free up space, leaving enough unallocated space behind the target partition, click "OK".

Step 3: Extend partition

1. Right-click on the target partition and select "Resize/Move".

Resize target partition

2. Drag the target partition handle into the unallocated space to extend partition.

Step 4: Keep all changes

Click the "Execute Operation" button and click "Apply" to keep all changes.

You will successfully move unallocated or the free disk space to C drive or any other partition in Windows 10/8/7 and get a bigger partition.

Easy and fast, in three steps, the free space is magically transferred from the big drive to the smaller one. 

Part 2. The Two Partitions are Not on the Same Disk

What if the two partitions are on different disks? For instance, the free space is on disk 0 while the C drive or D drive is on Disk 1. So, here comes the second part. To transfer or move free space or unallocated space to the other partition (on a different disk), you must covert your basic disks into the dynamic disk and then move the free space.

Step 2: Merge Two Disks

Select the full disk - disk 2, right-click on it and choose "Resize/Move".

choose the disk and resize

Use your mouse to adjust the disk size. Sometimes, the unallocated space is on the left of the partition you want to extend. If you want to move unallocated space, just drag the left partition handle leftwards to the size you want.

Click "Execute Operation" and you are able to merge space from one disk to the other.
