open Windows Explorer and select Storage Card. You can copy files from the Micro SD card to the vehicle
computer or double-tap the executable file to launch the application.

Flash Storage

In addition to the RAM-based storage standard on Windows CE vehicle computers, the vehicle computer is also
equipped with a non-volatile eMMC-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 vehicle computer includes two FFS partitions. These partitions appear to the vehicle computer 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 two FFS partitions appear as two separate folders in the Windows CE file system and are as follows:
Platform: The Platform FFS partition contains Motorola-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 vehicle computer 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
•
vehicle computer.

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" and "Platform" folders to the ActiveSync explorer. This is useful when installing applications on the
vehicle computer. Applications stored in the Application folder are retained even when the vehicle computer is cold
booted.
There are two device drivers included in the Windows CE image to assist developers in configuring the vehicle
computer following a cold boot: RegMerge and CopyFiles.
