Abstract
The amount of data that is written to disk is minimized when an overlay optimizer is used in conjunction with a write filter to prevent the overlay from becoming full. An overlay optimizer minifilter can be used to intercept writes that were initiated by the overlay optimizer's request to commit files cached in the write filter's overlay to thereby extract only the modified portions of the files that are actually stored in the overlay. The overlay optimizer minifilter can then write these modified portions of the files, as opposed to the entire files, in the overlay cache. Directory change notifications are also enabled when a write filter is employed as well as in other multi-volume filter environments.
