6 ff.h Common include file for FatFs and application module.
7 ff.c FatFs module.
8 diskio.h Common include file for FatFs and disk I/O module.
9 diskio.c Skeleton of low level disk I/O module.
10 integer.h Alternative type definitions for integer variables.
11 option Optional external functions.

13 Low level disk I/O module is not included in this archive because the FatFs
14 module is only a generic file system layer and not depend on any specific
15 storage device. You have to provide a low level disk I/O module that written
16 to control your storage device.
