Flash
1. SIMPL Program (.smw)
2. SIMPL+ Modules (.usp/.ush)
3. Operating System (.cuz file)
The 4MB flash memory consists of approximately 1.5MB used for firmware,
and approximately 2.5MB available for SIMPL, SIMPL+, and Web pages. The
files that reside in flash conform to a flat directory structure. The following table
presents the structure of the overall file system.

Although the file system is case insensitive, the case is preserved to maintain file
checksums.
Non-volatile
1. SIMPL+ Variables (Default if no options are specified, or using
"nonvolatile" qualifier or #DEFAULT_NONVOLATILE)
2.
Signals explicitly written to NVRAM* (by symbols such as Analog
RAM, Analog RAM from database, Serial RAM, Serial RAM from
database, Analog Non-volatile Ramp, Digital RAM, etc.)
*Commonly used for presets (volume/lighting/dial #s).
3. Portions of the NVRAM may be set aside for implementing an
“NVRAM Disk”. This can be used to provide file system access from
SIMPL+.
