Abstract
An overlay optimizer can prevent cross-volume moves to optimize the performance of a write filter. The overlay optimizer can be configured to detect when a file move is being attempted and can modify the handling of the file move so that a cross-volume move is not performed. In the case where the file move would result in a file being moved from the volume where the overlay cache is implemented, the overlay optimizer can create a copy of the target directory tree in the overlay cache and redirect the move to the newly created directory. In the case where the file move would result in a file being moved to the volume where the overlay cache is implemented, the overlay optimizer can forgo redirection so that the file will be moved within the same volume.
