• 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

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.
