Attaching File System Filter on actual device

Hello and Happy New years. I have developed a file system filters which
encrypts/decrypts specific directories. Everything is working fine on the
emulator, for I am using a shared drive on my local machine (it mounts, the
filter attaches, and everything is wonderful). However, I need to be able to
apply the filter to the main drive on an actual device. We are not an OEM so
my question is, is there another way to get the filter to attack to the
primary drive on an actual device. I was thinking perhaps, if such a method
exists, to map the primary drive to another name? Any guidance would be
greatly appreciated for we need to be able to encrypt/decrypt on the primary
drive. Thanks for any information given.

Regards,
Antoine

Define "Primary Drive" - the problem is that many CE devices don' have a
disk drive of any sort. So it's not clear what you are calling the "primary
Drive". It is possible to set up a filter for all block devices or for
specific ones via the storage manager profile settings. (It is not possible
to apply filters to the Object store nor the ROM file system.)

Hello Steve. By Primary drive I mean the boot drive with the windows
directory. Our software will install in the "/program files" directory and we
need to encrypt/decrypt user defined folders as well as some folder of
another installed application. Is that entire tree (\windows, \program files)
etc considered the Object Store?

Everying in \windows will be rom file system, unless you've mounted another
file system as root and shadowed Windows. Anything else will be the object
store, unless it's a physical device that you've mounted (hard drive, etc).
\Program Files is typically in the object store.
