I have to repeatedly run Defraggler to get my files defragged down to a decent level. It seems to me that Defraggler could follow Apples footsteps and defrag the file when it's closed. Thereby getting around my having to continually come back and defrag the drive. And possibly this would also solve the problem of my having to repeatedly keep running the program 5 to 8 times in a row to get the number of files needing defragging down to a decent level.
