Computer user would inevitably run into situation of insufficient partition space and should extend partition space to resolve this problem. How about GPT partition? Can we equally extend GPT partition? Definitely, GPT partition can still be extended as long as user employs a third-party partition manager supporting GPT disk. Speaking of such kind of partition manager, I would like to recommend MiniTool Partition Wizard.
In computer hardware, GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk. Although it forms a part of the Extensible Firmware Interface (EFI) standard (Intel's proposed replacement for the PC BIOS), it is also used on some BIOS systems because of the limitations of MBR partition tables, which restrict a disk partition's size to a maximum of 2.19 TB (2.19 × 1012 bytes) or 2 TiB−512 bytes (2,199,023,255,040 bytes or 4,294,967,295 (232−1) sectors × 512 (29) bytes per sector). GPT allows for a maximum disk and partition size of 9.4 ZB or 8 ZiB−512 bytes. As of 2010, most current OSs support GPT, although some (including Mac OS X and Windows) only support it on systems with EFI firmware. The widespread MBR partitioning scheme dating from the early 1980s imposed limitations which affected the use of modern hardware. Intel therefore developed a new partition-table format in the late 1990s as part of what eventually became UEFI. The GPT as of 2010 forms a subset of the UEFI specification.
Launch MiniTool Partition Wizard, select and right click the desired GPT partition which is to be extended, then click "Move/Resize".
In this window, user should set partition size via dragging the left and right arrows or entering accurate values in the textboxes. NOTE: user is recommended to check the small option at the top of this windows depicting "Using Enhanced Data Protection Mode" so as to ensure data safety.
After setting, click "Apply" to execute pending operation.
