• Minimize write actions to the disk.
For example, minimize write access to flash memory. Write cycles on flash memory are limited for
technical reasons.
Usage
FBWF is included in the Windows Embedded Standard 7 image and disabled by default. The configu-
ration of this component can be defined with the command line tool
FBWFMGR.EXE
.
To run to FBWF Manager, open the Command Prompt with Administrator rights.
Command Function Remarks
fbwfmgr
Shows an overview with current
status. ---
fbwfmgr /displayconfig
Shows current configuration. ---
fbwfmgr /enable
Enables the write filter. The protection is not effective until
the system is restarted.
fbwfmgr /addvolume c:
Adds a volume to the protected vol-
ume list. That volume will be protected after
the next restart.
fbwfmgr /commit c: \Test.txt
Writes the changes to the protected
file/folder. ---
fbwfmgr /addexclusion C:
\Test.txt
Adds a write-through path to the
exclusion list (file/folder). The exclusion is active after the
next restart.
fbwfmgr /removeexclusion C:
\Test.txt
Removes the write-through path
from the exclusion list (file/folder). The exclusion is removed after the
next restart.
fbwfmgr /h
Displays a helpscreen that explains
all commands and options availa-
ble. A complete reference can also be
found at the Microsoft Developer
Network (MSDN).
Additional Information
When specifying a file name, notice the space between drive name (c:) and file path (\Test.txt).
Considerations
• EWF and FBWF cannot be used simultaneously.
• FBWF can only protect formatted volumes. Do not move files between protected and unprotected
volumes.
• When the FBWF function is enabled and a large amount of data is written, the system memory
space will be reduced and operation may become unstable. To prevent this problem, it is recom-
mended that a large amount of data be written to a different location.
• FBWF supports only NTFS and FAT32 file systems.
• Automatic Adjustment of daylight saving time (DST) is incompatible with the File-Based Write Filter
(FBWF).
Additional Information
Refer to the Microsoft Developer Network (MSDN) for DST details.
