Running File Based Write Filter Command Line Options
There are several command lines you can use to control the File Based Write Filter
(command line arguments cannot be combined).
Caution
Administrators should use NT file security to prevent undesired usage of
these commands.
Use the following guidelines for the command line option for the File Based Write Filter
(you can also use the commands if you open an Command Prompt window by entering
command in the Run box):
Note
If you open a Command Prompt window and enter fbwfmgr /, all available
commands are displayed. For information on a command, use fbwfmgr /
help <command>. For example, for information on /addvolume, enter the
following: fbwfmgr /help /addvolume.
• fbwfmgr
With no arguments - Displays the File Based Write Filter configuration for the current

• fbwfmgr /enable
Enables the File Based Write Filter after the next system restart. The File Based Write
Filter status icon is green when the File Based Write Filter is enabled.
• fbwfmgr /disable
Disables the File Based Write Filter after the next system restart. The File Based Write
Filter status icon remains red while disabled.
• fbwfmgr /commit C: <file_path>
Commits the changes made to the file to the underlying media. Note that there is a
single space between volume name and file_path. The file path must be an absolute
path starting with \. For example, to commit a file C:\Program Files\temp.txt
the command would be fbwfmgr /commit C: \Program Files\temp.txt.
• fbwfmgr /restore C: <file_path>

directory is removed from the protection of the File Based Write Filter. The exclusion
will take effect after the next system reboot. The file or directory path must be an
absolute path starting with \.
• fbwfmgr /removeexclusion C: <file_or_dir_path>
