exFAT is the official file system of SDXC cards. Because of this, any device not supporting exFAT, such as the Nintendo 3DS, may not legally advertise itself as SDXC compatible, despite supporting SDXC cards as mass storage devices by formatting the card with FAT32 or a proprietary file system tied to the device in question.
exFAT is intended for use on flash drives and memory cards such as SDXC and Memory Stick XC, where FAT32 is otherwise used. Vendors usually pre-format SDXC cards with it. Its main benefit is its exceeding of the 4 GB file size limit, as file size references are stored with eight instead of four bytes, increasing the limit to 2 64 − 1 bytes.

To programmatically determine which file system a BDP contains, Microsoft specifies that one should inspect the BIOS Parameter Block that is contained in the BDP's Volume Boot Record .
exFAT does have a few advantages over FAT32, but they are irrelevant in many common use cases, where FAT(32) is used today as an exchange format on flash cards/sticks and where a relatively small number of large files is written once and not modified later on before the next delete/reformat (typically f.e. for usage in digital cameras ...
