GPT fdisk

In the eventuality that you need to keep various files and applications at separate locations than that of the system files or operating system files, then creating partitions on the hard drives connected to your computer is your best bet. GPT fdisk is a tiny CLI utility designed to help you create partitions using commands.
It is worth noting that the tool comprises of a set of tools, namely gdisk, cgdisk, sgdisk, and fixparts programs. While the first three components work on GUID hard drives, the latter has the role of repairing various types of damage that occurred to MBR disks. At the same time, the fixpart app enables you to make switches to primal to logical disk and vice-versa whenever required.
Generally speaking, Windows is unable to boot GPT disks unless the machine comes with Unified Extensible Firmware Interface (UEFI) firmware, a feature that is solely available for Vista operating system and newer. Consequentially, thanks to this tool, you can now make partitions that you assign accordingly even on older operating systems.
The utility can also come in handy for the times when you need to alter or create a hybrid MBR disk and therefore, ensure that your OS is capable of dual-booting. Last, but not least important, the utility allows you to create backups of partition tables from common disk files that you can restore at a later date.
