To make all the things on your hard disk well organized, you will need a partition manager tool for flexibly partitioning, optimizing and managing your computer. No matter whether you want to partition your hard drive for Windows installation, allocate free disk space, resize partition, or change file system of a partition or partition table, you can use a Windows partition manager DiskPart.exe to deal with it.
We want to use command line. Although operating a command line interface more difficult than a GUI, for more efficient to handle multi-task, some users would use command line rather than open many windows. Users only need to execute a few lines of command by utilizing their keyboards to control over both the file and operating systems.
Compared with using GUI, using command line to operate takes much less resources of computer system. Additionally, some tasks can only be performed by using command line. For example, you cannot delete recovery partition with Disk Management for it prevents users inadvertently applying actions leading to data loss, but you can use diskpart to do it. Therefore, users may be looking for a command prompt partition manager.
You need to open an elevated command prompt. To do that, you can type “diskpart” in the Search box, and right-click on the result diskpart.exe and then select Run as administrator.
If you are not familiar with diskpart, you can type “help” to see all the available commands. For example, to extend system partition using DiskPart, you can use the commands below.
● List disk
● Select disk 0
● List partition
● Select partition 2
● Extend
Then all the unallocated space behind partition 2 will be added into partition 2. If there is no unallocated space behind it, then diskpart cannot extend partition. In that case, you can delete partition using DiskPart behind to generate unallocated space.
Diskpart can also help you convert MBR to GPT disk. To do that, you need to use DiskPart clean command to delete all partitions on the hard drive, and then type “convert gpt”. If you want to manage partitions in an easier way without data loss, you can use command line partition manager software.
