Video Tutorial: How to merge partition?

EaseUS Partition Master only supports to merge NTFS, FAT12, FAT16 or FAT32 partitions. And the maximum size of the merged partition is less than 4TB (1TB=1024GB).


  • EaseUS Partition Master support merging partitions on basic disk only. It cannot merge dynamic volumes.
  • You can merge the NTFS partitions of different cluster size.
  • The two partitions which will be merged must be adjacent. It means that there are no other partitions except unallocated space between the two partitions which will be merged.
  • After merging completed, the size of the merged partition will be the total size of the original two partitions. If there is unallocated space between the two operating partitions, it also will be merged into new partition.
  • The operating partitions should not be a hidden partition. However, it can be the partition which has no driver letter.
  • In order to ensure a bootable system, the boot partition and system partition cannot be merged as the second partition. In other words, you cannot merge boot partition and system partition to another partition, only other partitions can be merged to them. This rule also applies to the partition where EaseUS Partition Master installed.
  • The unused space of the operating partitions should be more than 5% of the total partition space.
  • After merging a FAT 16 partition and a FAT 32 partition or both of the partitions are FAT16 file system, the file system of the merged partition will be changed into FAT32 automatically.
  • NTFS partition cannot be merged into FAT partition.
