3.9 BACKUP DIRECTORY FILE MANAGEMENT
All of the Windows CE 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 re-
booted or the battery pack is changed.
You can save your more important files that you don't want to lose due to mobile
computer re-boot, 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 will copy the contents including all sub-directories of \Backup\Windows
to \Windows.
Likewise, to maintain files that must be run at Windows CE 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 application programs will be run after any type of re-boot (both warm
and cold boot).
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. Re-install?". This message blocks the boot process.
