About disk partition software

Partitions are separated sections on hard drive to store data. Managing disk partition properly is one of the most important aspects to keep computer running at its best. Multiple partitions enable users to segregate data based on categories, for example, you can install operating system on one partition and keep multimedia data like movies and music in another partition. Partitioning a disk to two or more partition is a great solution to allocate data to specific location and keep operating system drive nice and neat. You can also format partitions into two different file system formats if you want to use them under different platforms, for instance, you may want to dual-boot your computer with Windows and Linux, you'll have to partition hard drive into at least two partitions, and format them to NTFS and Ext4 file system. In addition, you may want to shrink or extend system partition which might not be partitioned with reasonable size.

Disk partition software enables you to create, delete, resize, split partition on hard drives or USB drive. Although Windows Disk Management provides basic functions to manage disk space, it is not effective enough to deal with complicated situations, such as split partition, hide partition, clone disk/partition, convert GPT/MBR without losing data, permanently wipe data, convert primary/logical partition, quick partition a disk, etc. Thus, disk partition software is still preferred by both average and advanced users.
