exFAT (Extensible File Allocation Table) is a file system introduced by Microsoft in 2006 and optimized for flash memory such as USB flash drives and SD cards.[6] exFAT was proprietary until 28 August 2019, when Microsoft published its specification.[7] Microsoft owns patents on several elements of its design.[2]
exFAT can be used where NTFS is not a feasible solution (due to data-structure overhead), but where a greater file-size limit than that of the standard FAT32 file system (i.e. 4 GB) is required.
exFAT has been adopted by the SD Association as the default file system for SDXC cards larger than 32 GB.
