• 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
To run to FBWF Manager, open the Command Prompt with Administrator rights.
Command
fbwfmgr
fbwfmgr /displayconfig
fbwfmgr /enable
fbwfmgr /addvolume c:
fbwfmgr /commit c: \Test.txt
fbwfmgr /addexclusion C:
\Test.txt
fbwfmgr /removeexclusion C:
\Test.txt
fbwfmgr /h
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.
