To be simple, Windows 32-bit refers to operating system with 32-bit address bus and Windows 64-bit refers to operating system with 64-bit address bus. Thus, we can infer the so-called 32/64-bit stands for computer addressing space size. In the angle of CPU processor, 32-bit operating system is designed for 32-bit CPU while 64-bit operating system for 64-bit CPU. 32-bit CPU means the CPU could handle 32-bit data one time. No matter which kinds of operating system user uses, a outstanding partition magic software is a must for each computer as the built-in disk management tool of Windows operating system falls short of user's needs in terms of disk management. Therefore, I would like to recommend user MiniTool Partition Wizard, a third-party green and professional partition magic software.
Merge partitions under 64-bit operating system with MiniTool Partition Wizard
Launch MiniTool Partition Wizard:
Select any partition and click "Merge" at the toolbar.
Select the partition to be expanded and click "Next".
Select another partition to be merged to the previously-selected partition as a folder and specify a name for this folder. After that, click "Finish".
Now user could notice those two partitions have been successfully merged in this preview interface. However, user should still click "Apply" to really execute all pending operations listed at the lower-left corner of this interface. Then, this Merge Partitions operation would be completed by our partition magic software.
