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 and the next session.
•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>

•fbwfmgr /addexclusion C: <file_or_dir_path>
Adds the file or the directory to the exclusion list of the volume. That is, the file or 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>
