I don't recall mentioning TrueFFS, no. However, you can mount a persistent
filesystem, any persistent filesystem, as the root of the Windows CE
filesystem so that every folder that you see is persistent, \, \Windows,
\Temp, etc. In that situation, I don't think that you'd have to persist
anything but the registry (which you could store in the filesystem, as a
hive, also). What, specifically, are you worried about losing from the
object store when power is removed? That will help us assess what your
options are.

have to worry about files going away when power is removed. The format
of
the object store is not documented, probably changes on a daily basis
and,
other than the standard APIs for things like files, etc. doesn't provide
a
means to get to the raw data.

I currently working on a project that have requirements to save the
registry andobjectstoreon system power down. I currently
inplemented a power down interrupt that detects when the power key is
pressed by the user and flushes the registry to on board flash.
Unfortunately I have no idea how to flush or save theobjectstoreto
the onboard flash storage device. I know for flushing the registry, I
call the RegFlushKey(HKEY) function a number of times to flush the
full registry, but I don't know of a way to flush or save the
Objectstore. Would anyone have any ideas of where to start or where
to look to get documentation onsavingtheobjectstorefrom within the
WinCE OS image.- Hide quoted text -

Paul T. I don't understand. Are you saying that I need a TRUEFFS
(True Flat File System) mounted on the device.- Hide quoted text -

Paul T. I am new to the objectstore, so forgive my lack of
knowledge. From some of the information I read and recieved from
other sources, I gathered that the desktop shortcuts, directory
structure, folders, and databases are stored in the objectstore. I
want to make sure these items are saved during a power ON/OFF cycle.
I thought when you mentioned File system that you was refering to a
TRUEFFS, which is what we have partially integrated into the OS image.
