Note: Need to add links to this, and probably some exFAT stuff in general to the wiki when this page is done.


Disk Unit Addressing

Like FAT, exFAT saves file content in clusters, which are groupings of consecutive sectors (512-bytes each). It has the same problems as FAT in using these clusters as the addressable units, so like FAT the solution is to use sectors as the addressable unit instead. See FAT_Implementation_Notes#Disk_Unit_Addressing for more information.
