ff.h Common include file for FatFs and application module.
ff.c FatFs module.
diskio.h Common include file for FatFs and disk I/O module.
diskio.c An example of glue function to attach existing disk I/O module to FatFs.
integer.h Integer type definitions for FatFs.
option Optional external functions.
Low level disk I/O module is not included in this archive because the FatFs
module is only a generic file system layer and not depend on any specific
storage device. You have to provide a low level disk I/O module that written
to control the target storage device.
