I really like the new "boot-time defrag of system files" option in Defragler 2.00.221 beta, but it does not attempt to defrag the hiberfil.sys file (which, on my Win 7 64-bit system, is 3 GB in 2 fragments). It would be great if Defragler could defrag this file. Perhaps there could be an option where one could explicitly specify which files to defrag at boot time.
