Enhanced Write Filter
Enhanced Write Filter (EWF) protects a flash volume from write access and consequently, preserves the durability of the flash
device. EWF provides read and write access through a cache to the client instead of allowing direct access to a flash volume.
If EWF is activated, data is not stored to the flash. The data stored in the cache is only effective while the client is operating.
The cached data will be lost when restarting or shutting down your client. Therefore, to store the data written to the registry,
favorites and cookie folders, etc., the content stored in the cache should be transferred to the flash. An error message is
displayed when it is not possible to write to the cache due to a lack of memory. If this message is displayed, you have to
deactivate EWF to flush the EWF cache. The user can double-click the EWF icon on the tray at the bottom right of the screen
to call the EWF Manager. A user can also change the EWF configuration by entering EWF management commands at the
command prompt. This task requires the administrator privilege.
