Defraggler

CNET Editors' review

The Defraggler helps computer users who feel their system is running too slow. This simple program performs a complicated task that streamlines your PC's thought processes, but be prepared for a wait.

This free unlimited download attempts to bring order to your scattered RAM. When a file is created, portions of the item are spread into free spaces throughout the hard drive. As more files accumulate the computer has to work harder to piece together the puzzle that has become your specific file. This results in a slow computer. Defragmenting seeks out all these matching pieces and lines them up, making work easier and faster for the computer.

Defraggler downloads easily and is simple to understand. Its display shows users how much memory is available on their computers and also performs a search to show exactly how many files are fragmented in the entire computer. From here you can choose to defragment all or select specific files for defragmentation. Experts recommend regular defragmentation to keep computers running smoothly, so the Defraggler offers a scheduler to automatically run the program.

Defraggler is easy to understand and performs its job well. There is a strange chart along the top that seems to move for no real reason and is best ignored, but is only a minor annoyance. In addition, be prepared for a long wait time. Defragmenting a computer can take dozens of minutes. Still, if you want to improve computer performance, this is a great place to start.

    "Beat Smart Defrag and Auslogics Disk Defrag hands down!"

    April 22, 2012  |   By anniemj

    Version: Defraggler 2.09.391

    Pros

    Point and shoot, kills bugs dead. Auslogics' product reduced C drive fragmentation from 29% to 27% but could not improve on that number. Smart Defrag did absolutely nothing. Defraggler removed almost *all* fragmentation in one fell swoop.

    Cons

    A bit slow, but it gets the job done

    Summary

    I couldn't be more pleased with this free program. Thank you, thank you, Piriform!

    "system was more fragmented after running the program!!!"

    April 10, 2012  |   By register54321

    Version: Defraggler 2.09.391

    Pros

    the fact that I didn't need to pay any money to see how bad it is

    Cons

    took 2 hours to defray (which I can live with as I ran it overnight) but I started with 30% fragmentation and after 2 hours had 40%!!!

    Summary

    don't waste your effort or time. lots of other options.

    "Save your time, use another program!!!"

    March 16, 2012  |   By jaykorey

    Version: Defraggler 2.09.391

    Pros

    Pretty GUI interface; Pretty colors; "APPEARS" to preform a defrag of your hard drive. In short, EYE CANDY ONLY!!!

    Cons

    Confusing analysis results of hard drive. Questionable statics of hard drive health when compared to other hard drive utilites such as Maxtor or Seagate utilities. Suggest that you use the defrag utility created by J C Kessels at www.mydefrag.com. FAR SUPERIOR to Defraggler.

    Summary

    Don't even waste your time with Defraggler from Piriform. TOTAL waste of your time, especially if you're an IT professional with numerous clients and have to get their systems opoerating at peak performance!

    Pros

    Absolutely Nothing :(

    Cons

    Everything

    Summary

    This '' Program'' made my new computer work even worse. After installing it I felt that the boot up process took longer. This #### doesn't optimize your computer it makes it work slower ... I had to restore my Windows. Don't download it.

    "I really like it, but don't believe the health numbers"

    February 1, 2012  |   By mulderf

    Version: Defraggler 2.09.391

    Pros

    To be able to see how the program is working and to be able to differentiate between the types of data is real handy. I have always found the efficiency of this program to be a great feature.

    Cons

    It is nice to be able to see the health of your system, however, I have a new (not refurbished or returned) laptop that is only approximate 30 days old. However, the health display shows that the harddrive is over 753 days old. The flying hours show 494 hours. Since I have a record of when the system was built, I believe that these numbers are not accurate.

    Summary

    Except for some issues with numbers, the efficiency and ease of use of this software makes it more than worth while.

    "The Quick Defrag is Fast !"

    January 25, 2012  |   By Randy Bell

    Version: Defraggler 2.09.391

    Pros

    The Quick Defrag option is the fastest such feature available on any defrag utility I've used, with the possible exception of the one which comes with the Ashampoo WinOptimizer suite.

    Cons

    Apparently the full defrag can take a long time from others' comments here; but that is true for any defragger on a disk containing a lot of used space, being defragmented for the very first time.

    Summary

    I always choose Quick Defrag since I have PerfectDisk to do a thorough defrag. Remember that full defrag not only defragments files and folders, but also optimizes their placement on the hard disk. If you don't have much time to wait, choose the Quick Defrag option from the dropdown menu at the bottom. But this is excellent, especially considering it is free. Along with the free defrag utilities by Auslogis and IObit, this is one of the best ones.

    Updated on Feb 1, 2012

    Latest version is excellent! I like the "health report" on your hard disk, the tab with S.M.A.R.T. results for drives who support that, etc.
