his article will drive the use  the Flash File System Access available on the BGS2 Release >2.00/EHSx >2.00/PDsx/Pxx8 >3.20 modules through the use of the AT^SFSA command. .

General Overview of Flash File System Architecture (Byte numbers and file position/offsets)

Descriptions in the provided Zoc script do make extensive reference to byte numbers and file positions/offsets. To help understand how these values are updated during FFS operations, please have a look at the simplified graphical explanation below (Note: please note that this preliminary overview does not refer directly to the demonstration script and can be considered in isolation).

Zoc Script

The BGS2 Release >2.00 module is delivered from the factory with a default directory "voiceprompt" already loaded. For the purposes of this demo, all existing directories should be removed from the module before executing the script. The script does attempt to remove this directory (as well as others called DirectoryA and DirectoryB which are created later in the script) so as to return the module to a defined state. If these directories do not exist the module will return an ERROR, but this is normal and has been included in the script so that it can be repeated in succession without having to manually delete these directories.
