File-Based Write Filter (FBWF)

The File-Based Write Filter (FBWF) protects the memory of the client from being overwritten by any unauthorized user. By restricting excessive writing into the memory, the FBWF allows you to use the client for a long time. If you request I/O, the FBWF has the client perform its operations using the cache instead of the memory so that the memory can be protected.

The data saved in the cache is preserved while the client operates normally. It is removed when it is restarted or exited. To save the changes, you should write the relevant file onto the disk using the commit command. If you don’t know which file is changed, disable the FBWF, change it, and enable it again.

You can control the FBWF using the various options of the command at a command prompt.

FBWF Configuration

Current FBWF status : Displays the current status of the FBWF (Enabled or Disabled).

Boot command : Displays the FBWF command that will be performed at the next boot-up.

RAM Used by FBEF : Displays the size of the RAM the FBWF is using. If the current status is set to "Disabled", the used memory is displayed as 0 KB.

Threshold : Displays the maximum size of the RAM that the FBWF can use.

FBWF Command

Enable FBWF and reboot the system : Enables the disabled FBWF and restarts the client. If the client is not restarted, only the boot command is changed to BWF_ENABLE and the current status is not changed.

Disable FBWF and reboot the system : Disables the enabled FBWF and restarts the client. If the client is not restarted, only the boot command is changed to FBWF_DISABLE and the current status is not changed.

Commit files : Even if the disks are protected by the FBWF, you can add or delete the files you want to save on them. To write the changes onto the disk, click the [Write the changes to the disk] button.

Session Status

Current session : Displays the volumes being protected by the FBWF and a list of the folders and files on those volumes that are excepted from protection by the FBWF.
