3.15 BACKUP DIRECTORY FILE MANAGEMENT

All of the Windows CE 6.0 system files reside in RAM (volatile memory) except

for the Backup directory, which resides in FLASH (non-volatile memory).

Therefore the contents of the Backup directory are persistent even if the mobile

computer is rebooted or the battery pack is changed. You can save your more

important files that you don't want to lose due to mobile computer reboot, in the

Backup directory or create a sub-directory within Backup. Even though the

Windows Directory resides in RAM, it often contains files or sub-directories

created by the user or by installation programs that you don't want to lose at re-

boot. To keep these files persistent it is necessary to copy them to the directory

\Backup\Windows. This directory doesn't exist originally (only Backup exists),

and therefore it must be created. At the next cold boot, before activating the

shell, Windows CE 6.0 will copy the contents including all sub-directories of

\Backup\Windows to \Windows. Likewise, to maintain files that must be run at

Windows CE 6.0 startup, (i.e. .exe, .lnk, .vb, .htm, etc.), it is necessary to copy

them to the directory \Backup\Startup. This directory does not exist originally

(only Backup exists), and therefore it must be created. The applications

programs will be run after any type of re-boot (both software and cold boot).

However, since file system persistence is performed after the

“\BACKUP\Startup” folder execution, for those programs which depends upon

the DLLs and resources copied from “\BACKUP\Windows” to “\Windows”

during the cold-boot, the “\BACKUP\Windows\dl_startup” folder is to be

preferred to execute programs and applications, since the execution follows the

file system restore (and no DLL and resource dependence failure will occur). As

an alternative to the Safe Setup function, it is possible to copy the .cab files to

the directory \Backup\Cabfiles (the Cabfiles sub-directory doesn't exists

originally and must therefore be created) and perform a mobile computer cold

boot to have the application installed. Once these files are copied to the

directory \Backup\Cabfiles, the application will be run after each re-boot. From

the second cold boot on, a message may be displayed such as "<application

name> is already installed. Reinstall?". This message blocks the boot process.

X2 version, a 4GB DS type card is available as permanent general purposes

storage device (path = \Storage Card).
