Adding and Removing Programs
Programs pre-installed on your terminal are stored in ROM (read-only memory). You cannot
remove, modify, or accidentally lose this software. You may add programs and data files to
RAM (random access memory).
In addition to the RAM-based storage standard on Windows CE terminals, the PPT 2700 is
also equipped with a non-volatile Flash-based storage area which can store data (partitions)
that can not be corrupted by a cold boot. This Flash area is divided into two categories: Flash
File System (FFS) Partitions and Non-FFS Partitions.
FFS Partitions
The PPT 2700 terminal includes three FFS partitions. These partitions appear to the terminal
as a hard drive that the OS file system can write files to and read files from. Data is retained
even if power is removed.
The three FFS Partitions appear as three separate folders in the Windows CE file system and
are as follows:
Platform: The Platform FFS Partition contains Symbol-supplied programs and
Dynamic Link Libraries (DLLs). This FFS is configured to include DLLs that control
system operation. Since these drivers are required for basic terminal operation, only
experienced users should modify the content of this partition.
Application: The Application FFS Partition is used to store application programs
needed to operate the terminal. This partition includes the Symbol demo program,
which can be overwritten with your own program.
Data: The Data FFS Partition is optional and if present contains user data files
generated by your custom programs. The default PPT 2700 image does not contain
a Data FFS partition.
Working with FFS Partitions
Because the FFS partitions appear as folders under the Windows CE file system, they can be
written to and read like any other folder. For example, an application program can write data
to a file located in the Application folder just as it would to the Windows folder. However,
the file in the Application folder is in non-volatile storage and is not lost on a cold boot (e.g.,
when power is removed for a long period of time).
Standard tools such as ActiveSync can be used to copy files to and from the FFS partitions.
They appear as the “Application,” “Platform,” and “Data” folders to the ActiveSync
