On this page, you can learn how to resize partitions without losing data by using the [1] native Windows 11/10/8/7 Disk Management and [2] third-party EaseUS partition manager software. Both programs are good at extending or shrinking the NTFS partition. However, if your partition's file system is not NTFS but FAT32, you can only download the third-party program to change the partition size.

Can You Resize Partition Without Losing Data?
When it comes to resizing a disk partition, data safety is the first thing that strikes people's minds. Since resizing a partition is practically to shrink one partition or extend the other one, it's hard to start the first step before figuring out the risk, and many people are asking, "can you change partition size without losing data?" as well as the following frequently asked questions. You can check the quick answers.
Q1: Does resizing or moving the partition delete data?
Resizing & moving a partition can be two different things. Moving the partition is to adjust the forward and backward position of the partition on the disk and won't delete data. Is it safe to resize the Windows partition? Yes, the resizing partition can be subdivided into extending and shrinking partitions. Both operations don't delete data.
Q2: What does it mean to shrink a volume?
Hard drive shrinking is the practice of reducing the size of your partition to create unallocated space that you can use elsewhere. Before your computer can use the space on the hard drive to store data, the drive needs to be split up into separate areas called partitions.
Q3: Will I lose data if I shrink the volume?
Shrinking the partition won't cause data loss. If the partition includes unmovable files (such as the page file or the shadow copy storage area), the volume will shrink to the point where the unmovable files are located. That is to say, the used space with existing data is unavailable to shrink space.

Next, we will continue to give detailed steps to resize the NTFS partition. If you like it, share it with others in need.
Solution 1. Resize Partition Without Losing Data Using Windows 7/8/10/11 Disk Management
Windows Disk Management is, by default, installed on all Windows operating systems and Windows servers, and it offers the very basic functionality of extending or shrinking the volume of an HDD, SSD, or USB external hard drive. The "Shrink Volume" is 100% safe to ensure your data will not be affected. However, it's worth noting that the "Extend Volume" option CAN or CANNOT delete data, depending on whether there is unallocated space on the right side of the partition you're trying to enlarge.
Besides, Windows Disk Management only supports the NTFS file system. The upcoming tutorial is exclusively applicable to resizing NTFS partition only.
To shrink a partition without losing data, follow the step-by-step guide:
Step 1. Press the Windows + R keys to bring up the Run box, type diskmgmt.msc, click OK to open Windows Disk Management.
Step 2. Right-click on the partition that you want to decrease its size and select Shrink Volume.
Step 3. On the Shrink volume window, you can see the total size before shrinking and the size of available shrink space. Here, you need to enter the exact amount of space to shrink. Click Shrink, and it will be done in seconds.
Go back to the Disk Management interface, you can see the disk space has been decreased, and there is unallocated space available now.
To extend a volume without losing data, you need to do it carefully:
You can directly extend a volume if there is unallocated space on the right side of the partition you want to resize. Otherwise, the Extend Volume is grayed out and becomes an invalid option in Disk Management.
If there is no unallocated space next to the partition, you have to delete the adjacent partition to make unallocated space. Deleting a partition will lead to data loss, and you should back up files in advance.
If you do not want to delete the partition but must extend the partition, you can use the "Allocate Space" function of EaseUS Partition Master to directly add free space to the target partition, such as move space from d drive to c drive Windows 11/10.
Solution 2. Resize Partition Without Losing Data Using a Free Partition Manager
EaseUS Partition Master enables you to resize, move, create, and merge partitions with simple clicks without losing data. This partition manager supports both NTFS and FAT file systems. In other words, it allows you to not only resize NTFS partition but also to resize FAT32 partition. Moreover, the "Create partition" utility built in this program can help you create an NTFS/FAT partition. Its "Convert to NTFS" function enables you to convert FAT (FAT12/FAT16/FAT32) to the NTFS file system. Its "Merge partition" function enables you to merge FAT/NTFS partition to another NTFS partition.
Now, download EaseUS Partition Master and follow the steps below to resize a partition without data loss with ease.

Which Way Will You Choose to Resize A Partition?
To sum up, you can use either EaseUS Partition Master or Windows Disk Management to shrink partitions, and no data loss will happen. But if you want to expand the partition, consider the situation. Both methods are feasible if you can generate unallocated space on the right side of the target partition. If there is no unallocated space and you don't want to delete the partition, you'd better use EaseUS Partition Master for data security.
