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.
Enable disk write protection and restart your computer
- If the EWF is disabled, enable it. If this item is selected, the cache is flushed and the EWF is
enabled. After restarting your computer, the configurations and file system information for the
client are written to a cache. You can also perform this operation by entering “ewfmgr.exe c: -
enable” at the command prompt and restarting your computer.
Disable disk write protection and restart your computer
- This item is activated when the EWF is running. If this item is selected, the current states of the
client (saved in a cache) are saved to a flash volume and the EWF is disabled. After restarting
your computer, the configurations and file system information for the client are written to a flash
volume. You can also perform this operation by entering “ewfmgr.exe c: -commitanddisable” at
the command prompt and restarting your computer.
Write the changes to a disk
- This item is activated when the EWF is running. If this item is selected, the current states of the
client (saved in a cache) are saved to a flash volume. However, the state of EWF will not be
changed. You can also perform this operation by entering “ewfmgr.exe c: -commit” at the
command prompt.
You can view the configurations for the protected volumes by entering “ewfmgr.exe c:” at the c ommand prompt.
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 cach e
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
