What is the theoretical maximum support partition size for exFAT?

2 TB
4 GB
16 TB
128 PB

The correct answer is: 128 PB

The theoretical maximum support partition size for exFAT is indeed 128 PB (petabytes). exFAT, which stands for Extended File Allocation Table, was designed to be a more flexible file system that accommodates larger files and disk sizes compared to its predecessors, such as FAT32. While other file systems and formats have their limitations — for instance, FAT32 supports a maximum file size of 4 GB — exFAT significantly expands this with its capability to handle volumes up to 128 PB. This makes exFAT an ideal choice for modern storage solutions, including external drives and large-capacity USB flash drives, where large files and high capacities are common. In practical use, while the theoretical limits exist, the actual limits may be influenced by the operating system and the hardware implementations, but exFAT is built to support these vast sizes as part of its design.
