exFAT is not a file type. It is a file system of the FAT family. FAT comes from file allocation table and originated with the early FAT12 file system used on floppies, then to FAT16, and with WIndows 98 OSR2 added the FAT32 file system. The extended FAT file system, called exFAT for short is the latest and was made available for the desktop with Vista SP1 in 2008.
SDXC cards use the exFAT filr system.
exFAT (Extended File Allocation Table) is a file system designed by Microsoft for large storage devices like flash drives and SD cards. It supports larger file sizes and volumes compared to FAT32. exFAT uses a different structure for managing files and directories, allowing for better performance and compatibility across different operating systems.

Most memory cards are formatted with any denomination of the FAT file system (the most commonplace nowadays being FAT32, with a select few opting for exFAT - but not everything supports exFAT). However, you can format the volume with whatever filesystem you desire and what your requirements need (FAT, NTFS, EXT2/3/4, ReiserFS, HFS/HFS+, and so on)

exFAT file system for large external storage devices that you want to use with other operating systems. And FAT32 for small hard drives or USB flash drives because does not have as much overhead as NTFS.
FAT32 and exFAT (often mistakenly referred to as FAT64) are both file systems used for storage devices, but they have key differences. FAT32 supports file sizes up to 4GB and partitions up to 8TB, making it suitable for smaller drives and compatibility with a wide range of devices. In contrast, exFAT, which is designed for flash drives and external storage, allows for much larger file sizes (up to 16EB) and partitions, providing better performance for large files while maintaining compatibility across various operating systems.
Some popular disk file systems would be: FAT (FAT12, FAT16, FAT32, exFAT), NTFS, HFS and HFS+, HPFS, EXT2, EXT3, ISO 9660, ODS-5, and UDF. For a complete list of File Systems, go here: http://en.wikipedia.org/wiki/List_of_file_systems
