About exFAT Partition

exFAT, a file system introduced in 2006 by Microsoft, is optimized for flash memory like USB flash drives and SD cards. It is a modern replacement for FAT32, supporting very large files and storage devices. Besides, it also adds support for improved performance.

The exFAT file system can work with media devices including modern flat-panel TVs, media centers, and portable media players. Compared with NTFS, exFAT is supported by more devices and operating systems, but it’s not as popular as FAT32.
