3. The FBWF configuration window is considerably more complicated than the EWF setup. To enable FBWF

protection on your main storage drive, you will need to enable the filter by ticking Filter state enabled (A)

and Cache pre-allocation enabled (B). Next, select the drive you want to protect from the Volume

Configuration menu (C) and then click on the Protect button. Finally, click on Apply (E), or OK to set the

FBWF configuration.

Cache compression can be used on the overlay cache to minimize the amount of memory used. Cache

compression decreases performance when accessing protected volumes, and cannot be used with

pre-allocation. Cache pre-allocation sets the memory space available for the overlay cache when the

system starts up, instead of adjusting it as needed. It cannot be used with cache compression. The cache

threshold specifies the amount of memory that can be used by the write filter for the overlay cache. The

default value and size limits for the overlay cache vary by operating system.

4. Reboot the system.

5. Once again, open the system tray (located in the lower right corner of the desktop) and verify that the

padlock icon now shows that FBWF is enabled. The icon should have changed to a padlock displaying the

number 10, as shown in the figure at right.
