What is exFAT format?

exFAT( Extended File Allocation Table) is a flash drive format first used in 2006. Specially designed for flash drive and internal drive, exFAT is optimized on the base of FAT32. It can store files larger than 4GB, breaking the limitation of FAT32. With the exFAT file system, you can store individual files larger than 4GB on partitions larger than 2TB.

This file format can be used on many systems, such as Windows and MacOS X. If you want to store files larger than 4 GB on devices (such as the PS4), the exFAT can be the best choice.

exFAT vs. NTFS vs. FAT32: What's the difference?

exFAT, NTFS and FAT32 are three types of file systems.

It's the default modern file system on Windows 11/10/8/7, Windows XP, etc. With the directory and file permission, it provides users with a safe working environment. Besides, it improves reliability and disk performance by using an advanced data structure.

FAT32 is the oldest file system, since being created in 1977, it is widely used. Using the File Allocation Table, it describes the relationship between the allocation information and every cluster. If you want to locate the catalogue and files on the disk, FAT32 can work as the catalogue table of the system.

Compared with FAT32, there’s no realistic file/partition size on exFAT. In addition, the exFAT can be more compatible than NTFS. In other words, the exFAT can be regarded as the middle file system between NTFS and FAT32.
