JkDefrag v3.35

newly released today
http://www.kessels.com/JkDefrag/index.html
from the forum:
Changes:
- Upgraded to the Microsoft Visual Studio 2008 compiler.
- Logfile is now written in UTF-8, it used to be ANSI.
- Changed the default font into a smaller font.
- A change in the display code to respond faster to multiple redraw requests, for example when the users resizes the window.
- Rewrite of the subroutine that finds combinations of files to fill a gap, to make it faster.
- Changed the algorithm for "-a 6" (move to end of disk) to better fill gaps.
- Changed the way disks are accessed to accomodate special kinds of disks, such as virtual and encrypted disks.
- Bugfix in the screensaver for very long commandlines.
- Change in the disk analyzation code to fix a "zero bytes per cluster" problem.

 

Thanks for the heads up Mysteree :thumbsup

 

Awesome. Thanks, Mysteree.

 

Awesome. Thanks JkDefrag Rocks

 

is it better than defraggler?

 

IMHO, yes, it seems to be.. I have tried both, but somehow felt JKD did better.. but the way they work seems to be the same though.. But JKD apparently has a good optimization feature towards the end which would tilt the scale a bit towards JKD... So there.

 

What does the optimize thing do anyway?

 

Phase 3: Optimize

* On most harddisks the beginning of the harddisk is considerably faster than the end, sometimes by as much as 200 percent! See the link to "HD Tune" in the "See Also" chapter for a nice little free program to measure your disk. The default JkDefrag optimization strategy therefore moves all files to the beginning of the volume. It is intended for daily use and will simply fill gaps with files from above, very quick and with very little data movement.
* JkDefrag classifies files into 3 zones: directories (zone 1), regular files (zone 2), and SpaceHogs (zone 3). Directories are perhaps the most accessed data on disk, so zone 1 is placed at the beginning of the harddisk. After the directories comes a free area (see below), then zone 2 with regular files, another free area, and then zone 3 with SpaceHogs (less important files that take up a lot of space). The beginning and end of the zones is determined automatically, see the "-f" option.
* A running computer will create and delete temporary files like there is no tomorrow. If the harddisk were completely optimized then the only place for new temporary files would be behind all the other data. Which is rather slow. So JkDefrag maintains a free space of 1% of the total disk space between zone 1 (directories) and zone 2 (regular files), and between zone 2 and zone 3 (SpaceHogs).
* Sorting the files on your disk can give you even more speed. There are several sorting strategies to choose from (see the "-a" options). These are all very slow and intended for occasional use only.
* Windows reserves a percentage of the disk for the MFT (Master File Table), but can place normal files there if the rest of the disk is full. The files will remain there, even when there is enough space again. JkDefrag looks for files in the MFT reserved space and moves them to normal diskspace, making the reserved space available again for the MFT.

Why use this defragger instead of the standard Windows defragger?

* Much faster.
* Totally automatic, extremely easy to use.
* Optimized for daily use.
* Disk optimization, several strategies.
* Directories are moved to the beginning of the disk.
* Reclaims MFT reserved space after disk-full.
* Maintains free spaces for temporary files.
* Can defragment very full harddisks.
* Can defragment very large files.
* Can defragment individual directories and files.
* Can be run automatically with the Windows Scheduler.
* Can be used from the commandline.
* Can be used as a screen saver.
* Can be run from cdrom or memory stick.
* Sources available, can be customized.

Why use this defragger instead of a commercial or shareware defragger?

* It's free.
* Totally automatic, extremely easy to use.
* Optimized for daily use.
* Several optimization strategies.
* Directories are moved to the beginning of the disk.
* Reclaims MFT reserved space after disk-full.
* Maintains free spaces for temporary files.
* Can defragment individual directories and files.
* Can be used from the commandline.
* Can be used as a screen saver.
* Can be run from cdrom or memory stick.
* Sources available, guaranteed to be free of spyware, malware, nagware, and such.

 

It rearranges all your data to the fastest part of the HD disk. (outer rim)

 

Thanks for the heads up.

 

So, is this considered the best (or one of the best) defraggers? Also, is it always running in the background?

 

IMO, it is the best free defrag program, but I haven't done any formal tests with it. And it only runs on demand.

 

Yes, I think, along with others, that this is the best defrag solution. I don't think you can have it always running in the background. Plus, continuously running in the background overkill and not helpful.

Can JkDefrag do continuous background defragmenting?
In my opinion continuous background defragmenting and optimization is marketing hype and a bad idea. There is considerable overhead (CPU, memory, disk) that may actually make your computer slower instead of faster, and it will wear out and shorten the life span of your harddisk. I advise defragmenting once a day (via the Windows Task Scheduler) at the most.

 

Is it better than Auslogics Disk Defrag?

 

The general consensus is yes: http://forum.notebookreview.com/showthread.php?t=281714

 

Ok, thanks for the answers, downloading it now.

 

Yeah, JK Defrag is amazing.

 

Thanks for the update

 

JKdefrag FTW!!! my entire HDD is **** smooth now.
