Easily convert between primary and logical partition

In Windows OS, the first three partitions you create are primary partitions. These can be used to start an OS, and save user files. If you want to create more than three partitions, the fourth partition is created as an extended partition. An extended partition is a container that can hold one or more logical partitions. Some users want to manage hard disk space better for converting partition between primary and logical.

If there are already primary partitions on a disk, you will be unable to create more new partitions until one of them is changed to logical partition. As we know, Conversion should reformat the partition which leads to lose data, and no one wants to convert at the risk of losing all data.
