Introduction to the PanelView Plus CE Terminal 19
When the device is started in Safe Mode, the background service that
monitors the Registry for changes is suspended.
File Systems
The Windows CE operating system supports a DOS/Windows
compatible FAT file system that is implemented in a FAT partition on
the internal CompactFlash card, on the external CompactFlash card,
and a RAM file system that is implemented in system DRAM. Unlike
the CompactFlash, the RAM-based files are not persistent and are
reconstructed at every start-up. The RAM-based file system provides
the system root at the folder named My Computer. The file system can
be viewed and manipulated by the Windows Explorer utility and
DOS-like commands within the CMD shell. The CompactFlash files
appear at the root as the folders named \Storage Card and
\Storage Card2.
RAM File System
The RAM file system includes most of the known, standard Windows
folders, such as \Program Files, and most importantly, the \Windows
directory, where much of the system code and behavior resides at
runtime. The RAM-based file system is organized as follows:
