What is the difference between exFAT and FAT32 and NTFS?

Windows supports three kinds of file system and you can see them when you format an internal drive, external drive or removable drive. They are NTFS, FAT32 and exFAT. Partition file system determines how you store information and what you can store and how you access those data on that partition.

NTFS, as the most modern file system, has been used in Windows system drive by default since it works perfect with large-sized partition and file, and has many advanced properties that are helpful for operating system.

FAT32 is the first of three file systems available to Windows so it has strong compatibility among different operating systems and old devices. Nevertheless, it also has obvious disadvantage that is not practical. For example, 4GB maximum file size.

exFAT makes up for the limitation of FAT32 so that you can store file that is larger than 4GB. It also works well with large-sized partition and file. However, exFAT has less compatibility than FAT32 yet still more than NTFS’s. For user who requires strong compatibility and stores large files on device, exFAT would be the best choice.
