    It's definitely faster by far than any other defragger I've used, and it's passed scrutiny at Gizmo's and Major Geeks. In spite of one past instance of malefaction, in which IOBit was caught stealing code from other security software companies, and although I have yet to install this very latest version of IOBit defrag, I am reasonably comfortable giving it a...wait for it.....5!

    The link for this newest version game me the 3.0 build, not the 3.1.
    Iobit site doesn't even have this build up.

    This good tool runs only at WinNT or hiher, not on 9.x!
