RL-FlashFS include files in \ARM\RV31\INC:

File Name	File Type	Layer	Description
absacc.h	Header File	All layers	Header file to locating variables at absolute addresses at C level. The file is included from the file File_lib.c. Code changes are not required.
File_Config.h	Header File	All layers	Header file with common definitions. Code changes are not required.
File_lib.c	Module	All layers	System configuration file outlining library functions. Code changes are not required.

RL-FlashFS library files in \ARM\RV31\LIB:

The RL-FlashFS libraries FS_ARM_L.lib, FS_CM1.lib, and FS_CM3.lib include code that is capable of supporting a file system with long filenames in applications that you develop. Although the Microsoft US patent for long filenames has expired, Microsoft's European patent concerning long filenames (EU Patent EP0618540) is still active. Distribution of applications developed in Europe that include a file system with long filenames is only permitted if you first obtain a license from Microsoft for such a file system.

As an alternative, the libraries FSN_ARM_L.lib, FSN_CM1.lib, and FSN_CM3.lib are not capable of supporting a file system with long filenames.
