A defrag-to-shutdown tool for 2000, XP or better operating systems. From version 2.0 on, this tool works without any dialogs. It auto-scans for fixed disks and defrags them individually at high-priority. This nifty program either sits in your systray waiting for a double-click, or it runs immediately (default)... depending on the commandline parameter (7 different parameters available) you gave it at startup.
