Enhanced Write Filter or EWF is a component of windows xp embedded and windows embedded standard 7 which filters writes to another medium instead of being physically written to the volume itself. EWF allows the writes to be discarded or committed to the physical volume later (either directly or through inaction based on the configuration) As this minimizes writes to a specified hard disk, EWF and FBWF (File Based Write Filter) have become popular in enthusiast computing as a way to decrease wear of Solid state drives on NetBooks and CarPC's.
Operating Modes
EWF has three main operating modes: EWF Disk, EWF RAM, and EWF RAM Reg. The modes differ in the configuration of the Enhanced Write Filter and the location to which the drives are diverted.
