Flash File System; Platform Folder - Symbol PDT 7500 Series Product Reference Manual

Flash File System

The Flash File System is divided into three different folders in order to isolate terminal specific
files from application files.
Files that exist in Flash File System folders are initially programmed via TCM Hex files. Any
files that reside in the Flash File System are not lost after a cold boot. Similar to a desktop
hard drive, the files are added or deleted and are persistent when the terminal is powered
down.
The primary benefit of storing a file in one of the Flash File System folders is not losing the
file when the terminal is cold booted. The primary benefit of storing a file in the Object Store
is speed. Generally, a file can be accessed faster from RAM than from ROM.
Store files that need to be accessed from the Object Store (for faster access or some other
reason) and preserved over a cold boot in the CopyToRAM folders in the Flash File System.
Files stored in CopyToRAM folders are copied into the Windows folder of the terminal when
the system is cold-booted.

Platform Folder

The Platform folder is designed to hold all of the terminal specific files required by
applications that run on the terminal. These include Windows CE operating system files and
Symbol Value Add drivers and files. With the exception of software upgrades to specific
drivers using files provided by Symbol, the application developer should never have to modify
the Platform folder. The Platform folder is divided into a number of sub-folders, each
containing specific types of files. These folders are as follows:
Platform\CopyToRAM – The files in this folder are copied to the Windows folder
!
after a cold boot. Use this folder for files that need to run in the Windows folder.
Platform\System\Bin – This folder contains Operating System files (.exe and .dll
!
files).
Platform\System\Fonts - This folder contains Operating System font files. These files
!
are copied to the Windows folder when the system is started.
Platform\System\Regs - This folder contains Operating System registry settings.
!
Refer to RegMerge Operation
Platform\System\Wav - This folder contains Operating System audio alias-ed .wav
!
files. These files allow terminals without audio circuitry (such as the PDT 7500
terminal) to perform some other action when a System .wav file plays. These files are
on page 4-6 for details on the operation of .reg files.
