Hi all,

-Don't know whether anybody had posted this, but I've been using it for months now (since March 2007) & decided to share it. JKDefrag is getting better by every new version. Easy, stable & fast - automatically defrag all accessible NTFS & FAT* volumes. Highly customizable - have command line version, too.

-Get it here : JKDefrag v3.26

Regards.

I tested it, the freeware is good and work as claimed, you can get the GUI version at http://www.emro.nl/freeware/

i want to try it..thank for give the link..

yeah, i tested the jkdefrag gui version, the outcome is promising, after defragged, the fragment is 0 to 1% (analyzed with windows defragger and perfectdisk)

just try dis software...good performance..recommend to all of u...

edit- sorry

how 2 change it so tat it can defrag other HD??

-Just connect all drives/volumes that you want to defrag BEFORE you start JKDefrag. It then will automatically defrag them.

Regards.

can it run on Vista x64??

-Yes, there's a special build for X86-64 Windows. Check out the site.

Regards.

thanks for sharing.will not using diskeeper anymore

just uninstalled perfectdisk to save space (serving me for many years tho'), switched to this as well

-That's good to hear. We can help to contribute too; there're still many rooms for improvement - just give a shot at the source code (for programmers - e.g. integration/usage of XP/Vista Prefetch data). For normal users, use, test, & give your feedbacks.

Regards.

thanks for sharing. great and simple software

I'm currently using Diskeeper and somehow the *ahem* problem cause it not to auto defrag anymore.

My main purpose of using a third party software rather than the windows default defragmenter is the ability to auto defrag.

Just wanna ask if this software has the ability to auto defrag in background using very low resources?

Will download it straight away after the answer

-Hmm, it should be able to. Just read the "Frequently Asked Question" section on the main page; you'll be guided how to use Windows' Task Scheduler to it. Furthermore, the GUI version should be easier.

Regards.

@bluesky87, it doesn't has background auto defrag as the author doesn't recommend it as well.

-Oh, I didn't catch the word background before. Yes, why should you defrag all the time as this will wear out your disk faster? Also, if 2 program accessing same files (the program you're running & the background defragmenter), wouldn't this will actually slow you down?

Regards.

Yes dude..good software...i already use it...

thx a lot.^^..nice stuff TS got ther

sotong168 thanks you so much for the info.

Musafir_86 thanks for your advise. My thought was actually the duration of defragmentation which means how long will it take to defrag my hdd. I didn't know that defraging all the time will actually wear out my drive. I see you've got your point and I think I'll either roll back to the default windows defragmenter or give it a shot on this piece of program

Thanks anyway.

thx for share, a good defrag software. not tat lag while using it

i'll switch to this soon. how does it fare against Auslogics Disk Defrag (which is free)?

1 thing i don't like about perfectdisk and diskeeper is that it has a service running in background (eating memory), although i don't use auto-defrag/schedule.

i prefer Auslogics Disk Defrag..

tried it... do speed up my booting n shutting time... especially i using Vista, which always slow slow booting n shutting...

way better then Vista own defragmenter... which took HOURS to complete the defragment.... JkDefrag took less than 1 hour to defrag all my drive...

Downloaded and tested. It actually took quite long to defrag my 200gb drive which separated into three partition. I don't really know the details about defragmentation but what I get after defraging is it speed up my shut down time and when I analyze using the default Windows Disk Defragmenter, those color were arranged accordingly unlike last time even after defrag still look messy.

are you guys using the GUI version or the original version?

Actually what's the different? Sorry for the noob question but what is GUI? I just went to their website and download, extract and run JkDefrag only

GUI is user friendly as it provides options interface while non-GUI need to use command to customize. I recommend GUI version.

Extremely light weighted defragger! Recommended

Thanks for your explanation. The one I'm using is the GUI version not the command version.

i using the ori version... just click and it run itself....

does this software have scheduler ?

Yep u bet
Light and yet quite complete.

hmmmm.....
seem to be somehow i found what i want out of no where
thx for the intro TS

hei guys..download Jkdefrag GUI here..they are all made by different authors, so pick one you like..see screenshots on those pages

http://thommy88.th.funpic.de/index.php?men...ragstarter.html
http://www.emro.nl/freeware/

alright..this is cool...i defrag my laptop very often...and this turn out to be a very good tool for me..

thanks...

Thanks for the update!

which one is better?

i've tried it but can tell me in what sense this JKDefrag is better? I can only say that this program is faster than the normal 1.

i am using the first 1.it will auto update when there is a new version and will defrag when screensaver running

can i noe the automatic defragment of diskeeper really hurts the hardisk???
it will wear out the hardisk faster?
then why the diskeeper introduce such function and is still get nice response?

i also suspect sometimes...i defrag kinda very often...and i guess maybe this is one of the reason that i kena the windows error blue screen...despite i do downloading awys also...

correct me if im wrong..thanks in advance...

-Hmm, you can refer the FAQs (answered by JKDefrag author himself) on the JkDefrag main page. Also, here's what Executive Software said about that : http://www.diskeeper.com/diskeeper/myths/hard-drive-wear.asp.

-I'm pointing that continuously defragmenting your harddisks in the background will wear out the disks. Why? Refer to above link (Diskeeper site); they talk about numerous disk accesses (read/write ops) required for fragmented files. Then, how about constantly defragmenting some files as they are modified? The original programs alter the specified files, then the Diskeeper touches it (to defrag) again. Doesn't that increases disk access counts? Note that this only affects files that are modified frequently, and/or change in size (getting bigger/smaller) during modifications, or different clusters being used. For static files (even they're accessed many times), this doesn't apply as Diskeeper doesn't touch them.

-This is based on my personal calculation. Hope that help. Thanks.

Regards.

JKDefrag v3.30 - Download (ZIP)

JKDefrag v3.30 (November 30, 2007)
Changes:
- FAT disks are now analysed by directly reading the FAT from disk. This is a lot faster, and finds more system files.
- Changes to the graphics routines in the Windows and screensaver versions. The screen is now updated faster and more efficiently.
- Added the "average begin-end distance" statistic to the report.
- The commandline is now scanned for the "-l" logfile option before anything is written to the logfile.
- Changed the progress counter for the Fixup phase.
- Added a second fixup phase after optimizing "-a 3" to catch files that could not be moved the first time.
- Bugfix for automatic processing of volumes that are mounted on a directory instead of a drive letter.

Today is download softwares for me...have to try this also..

please try JKDefragGUI 1.0

very nice

thanks for the nice software...

defragmentation increases wear and tear. not recommended to defrag too often.

How fast is fast you guys defrag? I DL JKDefragGUI and start defrag yesterday at 6pm. But now 9.45pm still defrag at 72%. Is there some problem with the pc?
And this JKDefrag can't choose the drive to defrag. Once I double click the JKDefrag, it go to C drive and defrag straight away. Am I miss something?
