Hi
I think it's time to update few things here... Iobit smart defrag is no more in beta now, final version is already released... and the best one according to me... the only free defrag that gives you real time defragment.... the best one without any doubt...

Smart Defrag seems to work the best for me, fwiw; slower than jkdefrag to work but (subjectively) noticeably faster disk performance that lasts longer between defrags.

Has anybody heard of or used SysInternals PageDefrag version 2.32 or ContigDefragmenter version 1.55? I'm just wondering as the reviews at download.com are pretty good regarding Page Defrag & would like to know more before I try either of these. Thanks!

Hi ,
From a non tech. type--here's what works for me:

1. Run 10bit smart defrag, it only left 6 or so files fragmented on my two discs it even zapped a mega cluster of fragments in my "pagefile.sys" folder.

2. Run Defraggler and use the individual file defrag option to zap any obstinate leftovers.

For the first time I have NO fragmented files--- have left 10bit smart defrag on "auto" to keep it that way

My vote is for JKdefrag as well.

Granted, it ran for about 50 hours on my machine (!!! ... but seriously, it was over 3 harddisks, 2 120's and a 160 GB, which were badly badly badly fragged and I couldn't run the Windows Defragger because of not enough free space), but the difference is certainly noticable (faster boot, faster loading of apps/games). Also, the JKdefrag website gives a lot of good general info about harddrives and how files are stored and read. Recommended reading no matter what tool you go for at the end of the day.

I hear good things about Piriform's Defraggler, but I simply can't yet bring myself to try it again after the royal mauling that it put my harddrive through the first time. Seriously, shortly after the defrag started I got weird errors, couldn't open certian files anymore, and getting yes/no dialogue boxes which were everal screens wide (!!! ... I don't know how that works either)! Eventually restarted, and oops, where did Windows go? Attached the harddrive to another box and I could then browse my files, but not open them. Viewing using a text viewer worked, but inside certain .doc files, for example, I could see text previously belonging to OTHER .doc files ... ! A definite scrambling of the harddrive there.

Anyway, I'm sure Defraggler works perfectly fine now and I just need to get over the fear factor. I gladly use Piriform's other stuff, CCleaner and Recuva, but Defraggler still has to grow on me ...

Anyway, my 2 cents. Cheers,

portable version of JkDefrag at http://portableapps.com/apps/utilities/jkdefrag_portable

For me Jkdefrag is the best program even compared with the paid ones.

I have scheduled it to defarg when my computer boots and with the default options, just specify the speed of 25 %.

You guys have either not seen or used Defraggler (http://www.defraggler.com). It made a big difference to my system. My 2 year old Athlon64 3000+ WinXP-SP3 system shuts down in less than 5 seconds and is also much faster while booting up. The time it takes for Defraggler to defrag a hard disk is a fraction of what it takes for jkdefrag, or even Auslogics. You can choose to defrag individual files, or the entire disk, or even defrag your free space. There just cannot be another software, with so much functionality and performance packed into it, that could make any further improvement in system performance. And the best part is it is just a 0.5 MB download. I highly suggest you give this software its rightful place here.
For best results I recommend using XP Antispy (remember to set the system to not to clear the page file at shutdown, unless you are a terrorist plotting against the US), followed by KCleaner, Eusing Reg Cleaner, Auslogics Reg Defrag and finally Defraggler. I would like someone to tell me if he could get any better results than that.

In what way is the product that comes with Windows inferior to some of these other defraggers?

try out Defraggler, its made by the ppl that made CCleaner, and its pretty good

How important is it for the defragger to use the Windows Prefetch layout.ini to optimize the position of the most-frequently used files? There are a lot of good articles that say that Prefetch is important for performance.

JKdefrag doesn't use Prefetch data, and says its failure to do so is an issue; (it messes up the Prefetch optimization).

IOBit has virtually no documentation, but a forum moderator says it optimizes like Prefetch (but whether that means it literally uses the Prefetch layout.ini data is unclear).

I haven't used any of the others, so I don't know about them -- but would like to :-).

Hi
Iobit smart defrag final version has been released....

Hi, I have used : IObit SmartDefrag on both XP and Vista and I´m impressed
by the simplicity, speed and hasselfree performance .
I´ve read about other defraggers witch could be an alter to IObit but I
am really satisfied with IObit and will keep run it .

I recommed JkDefrag & the JkDefrag GUI. The GUI makes it a lot easier to access the various options available.

Just unpack the GUI, with 7-zip of course, to the same folder that the JkDefrag program files are in and you're in business. I love that it is portable since my friends/family depend on me to keep their PCs running smoothly. Plus it works on my Vista x64 as well as XP 32bit.

I looked into that Windows command line option for 'defrag c: -b'. It didn't make a difference on my desktop computer. I'll try it on my wife's laptop later and update my post on the results.
