    "I find JkDefrag a MINDLESS app."

    January 20, 2009  |   By caenet


    free & portable


    separate GUI; slow; mindless;


    I had hopes for JkDefrag because JkDefrag is a portable app; however,
    upon launching JkDefrag for the first time I was surprised to see that JkDefrag immediately
    began to defrag drive C:\ without giving the user any option of what (if anything) to do.
    I decided to let JkDefrag finish defragmenting C:\ and was then surprised that JkDefrag
    immediately started to Defrag D:\. I had no choice but to close the app's DOS like window.
    I suppuse JkDefrag would have gone on to Defrag my drives F:\, K:\, V:\ & X:\ ... mindless.
    I then tried JkDefrag on my oldest XP laptop (with an already fully defragged C:\ drive).
    Unlike AusLogics or Windows defrag which defragment this old, slow XP laptop's HDD quickly
    and even quicker when the HDD is already defragmented, JkDefrag ran all night & half the morning
    defragmenting an already fully defragmented HDD ... mindless ...

    Looks like someone failed to read anything about the software before trying it.

    JKDefrag does not just defragment drives, it optimizes them by placing most important files at the front of the drive (where your drive is fastest) and least important files at the rear of the drive (where it is slowest).

    What does that mean for a perfectly defragmented drive that has never been optimized? The files will have to be rearranged to optimize the drive. After JKDefrag has been run once, the drive is in order, and JKDefrag will run much faster on subsequent attempts.

    If you're not happy with the way it attempts to defrag all drives (I personally am, because I can run one program with no input and it hits all my drives) feel free to run it command l
