Using the File Based Write Filter (FBWF)
The File Based Write Filter provides a secure environment for thin client computing by protecting the thin
client from undesired flash memory writes flash memory is where the operating system and functional
software components reside. By preventing excessive flash write activity, the File Based Write Filter also
extends the life of the thin client. It gives the appearance of read-write access to the flash by employing a
cache to intercept all flash writes and returning success to the process that requested the I/O.
The intercepted flash writes stored in cache are available as long as the thin client remains active but are
lost when the thin client is restarted or switched off. To preserve selected changes, the selected files of
the cache can be transferred to the flash on demand by using WDM software or manually by using
Commit in the File Based Write Filter Control dialog box; alternatively, if the files affected by the changes
are not known, the changes can be made after disabling the File Based Write Filter using the File Based
Write Filter Control dialog box, and then re-enabling the File Based Write Filter, For more information,
see Setting the File Based Write Filter Controls.
The File Based Write Filter can be controlled either through the command line (fbwfmgr) or by double-
clicking the File Based Write Filter icon in the Administrator system tray. The File Based Write Filter can
flush specified files to the flash from cache only up to the point when the commit is performed; if more
writes are performed on the files that have been flushed, then these files must be flushed/committed
again if the additional changes also need to be preserved.
The File Based Write Filter can also be enabled/disabled through the command line or through the File
Based Write Filter Enable/Disable desktop icons. The status (enabled/disabled) of the File Based Write
Filter is displayed by the File Based Write Filter status icon in the system tray green indicates that the File
Based Write Filter is enabled and red indicates that the File Based Write Filter is disabled.
