How to manage / resize Partitions on Windows 10 without loosing data?

There is a lot of freeware available over the internet to resize/modify the existing partitions of Windows 10. If you have purchased a new computer with a pre-loaded Windows 10 operating system, you may have only one partition. If you have already created several partitions and later you want to resize or merge them. Everything is possible without any third-party tool. There is no need to hire a technician to resize or modify the Windows 10 partitions. It is so simple to play with existing partitions.

Windows 10 ships with a built-in tool that is called Disk Management. Disk Management is the tool responsible for creating, delete, modifying, and formatting the partitions. Even you can change the drive letters with the Disk Management tool without downloading any third-party software.

You will find the Disk Management window in two panes. The top pane shows a list of volumes, while the bottom pane shows a graphical representation of available disks and the volumes that exist on each disk. If you select a volume in the top pane, the bottom pane will show the disk that contains that volume. And if you select a disk or volume in the bottom pane, the top pane will show the corresponding volume. If you have more than one hard disk installed on your computer, it will show Disk 0, Disk 1, and so on on the bottom pane.

How to resize a partition on Windows 10?

To resize the existing partition, you need to shrink the volume, so the unallocated space can be allotted to another volume/partition.

Step 1. Click on the Start button and type diskmgmt.

Step 2. From the search results, click on “Create and format hard disk partitions” to launch the Disk Management tool.

Step 3. Right-click a volume/partition in either pane and select the Shrink Volume option.

Note: You can only shrink a volume if it has enough free space. In my example, we are shrinking “Volume F,” which has enough free space.

Step 4. It will open a new window with a shrink name; you can specify the size to shrink. By default, it will automatically select the maximum available free size to shrink, which is editable.

Step 5. Once you have entered the size to shrink, click on the Shrink button.

Step 6. Once the shrinking will be completed, you can see that the space is unallocated.
