Editors' review

Join your hard drive fragments together into a tight bunch with this freeware. Auslogics Disk Defrag's interface couldn't be any cleaner or easier to use.

Choose a hard drive from an easy-to-read pull-down menu, and Disk Defrag instantly displays the drive's size, and used and free space. The program even displays a pie graph for visual learners. One click starts the defragmentation process. The program's defrag process screen displays another handy visual. A sector map makes it easy to see how much of the drive is fragmented, allocated, or free. As the program churns away, the defragged sectors are displayed in blue.

We found the program fast, even on older XP systems. A handy HTML report is prepared after each defrag session. A summary displays the total files and folders defragged, while the detail section lists the defrag outcome for each file. We only wish a final sector map was included in the report. Novices to system administrators will love this easy-to-use hard drive defrag program.

    "Does not coalesce free space"

    September 02, 2014   |   By ChrisAllen CNET

    Version: Auslogics Disk Defrag 4.5.5


    Defrags all files except a dozen mysterious "unmovable" small files. oooWOOooo Gives option to move files into "fast" region near front of disk.


    Does not coalesce free space. So it isn't a complete defrag.

    "Last 2 versions didn't consolidate free space, and...!?"

    June 18, 2014   |   By scottls59901

    Version: Auslogics Disk Defrag 4.5.5


    It's Very Fast, and free.

    Seems to improve performance.

    I've tried Many free/paid defrags, but this is the only one that increased performance.


    I Run as Admin after 2 no-activity restarts (then wait 30min for HD to settle down...), move system files to a faster part of the HD, but after restart there are always large areas of free space not consolidated?

    If I use their delete Junk files option..., performance decreased.

    My AV didn't like the harmless PUP AD, in their latest version.


    Old version has to be uninstalled first, or installer will offer to uninstall then (I had to temp disable my AV until after restart).

    I submitted a detailed trouble report to Auslogics Tech Support, but no reply as yet?

    I tried their Pro version, with it's umpteen defrag choices (Very Confusing!), but it's always running... slowed my computer (their tech support couldn't help?).

    Updated on Jul 3, 2014

    On my 1st AV scan the download was deleted, because of the non-malicious PUP.

    "Seems best"

    June 16, 2014   |   By Scree

    Version: Auslogics Disk Defrag 4.5.5


    Pretty well designed and does the job well.


    Last update sneakily added a one-time scheduled task AD display!


    This still seems to be the best of the free defraggers around today, but they are starting to get shady with pushing ads. Oh the tradeoff of being free...
