GPT is short for GUID Partition Table; it is a standard for the layout of the partition table on a physical hard disk. Compare with the Master Boot Record (MBR) disk, GPT disk stands out in the following aspects:

►Allows up to 128 primary partitions. MBR disk can only support four primary partitions and an additional 124 partitions created in extended partitions

►Allows the partition size greater than 2 terabytes (TB), which is the limit for MBR disk

►Provides greater reliability because of replication and cyclical redundancy check (CRC) protection of the partition table


If using built-in Windows Disk Management to resize GPT disk partition we will get some limitations. So, the latest AOMEI Partition Assistant Professional provides enhanced GPT disk management like resizing GPT disk partition, extending/shrinking partition on GPT disk. And if there's a BitLocker partition, you can also resize it with this tool.
