How do I . . . defragment a hard drive with UltraDefrag 3.1.0?

UltraDefrag is one of the fastest defragmenting tools available. And while it's working its speedy magic, it uses very little resources. Jack Wallen explains how it works.

Let's face it, most of the defrag utilities that ship with any given Microsoft Windows operating system are less than up to the task. They are typically slow and lack much in the way of functionality. Fortunately, there are third-party defragmenting tools out there that do their job and do it well. Of those tools, one is the open source utility UltraDefrag.

This blog post is also available in PDF format in a free TechRepublic download.

UltraDefrag is one of the fastest defragmenting tools available. And while it's working its speedy magic, it uses very little resources. The reason UltraDefrag is so speedy is because it uses a kernel-mode driver to do the work.

Some of the features of UltraDefrag include:

  • Able to defrag at start up (similar to chkdsk)
  • Available for both 32- and 64-bit architecture
  • Can defrag a single file or entire directory
  • Includes command-line version
  • Debug logging
  • Uses very small footprint
  • Includes portable version that can be installed on USB drive and used without installation
  • Generates HTML reports upon completion

Getting and installing

As with any Windows application, the installation of UltraDefrag is simple. Download the UltraDefrag installer (make sure you download the file for the proper architecture), double-click the file, and answer a few questions. You will notice that there are some optional components for the installation:

  • Documentation - Help files
  • Scheduler.NET - Scheduler for UltraDefrag (requires NET Framework 2.0)
  • Portable UltraDefrag package - Build a portable package for a USB drive
  • Context menu handler - Defrag volumes from context menu
  • Shortcuts - Icons for menus and desktop

I would suggest you install all the options. Having the USB version of this application is worth the price of admission alone.

Basic usage

When you first fire up UltraDefrag, the main window should look fairly familiar (Figure A), because it looks similar enough to any other defragmenting utility out there.

Figure A

UltraDefrag has a very straightforward GUI. You can even change the UI font from within the Settings window.

The basic usage should need fairly little explanation:

  • Highlight the volume you want to check.
  • Click on the Analyze button.
  • Click the Defragment button if needed due to volume.
  • Read your reports if necessary.
After you analyze a volume, you will see a very clear representation in the main window (Figure B). Depending on the results of the analysis, you may or may not want to defragment.

Figure B

A defrag is needed.

As you can see, there are enough fragmented files that will make me want to go ahead with the optimization (compacting) of the volume.

If you do click the Defragment button, you will be shocked at how quickly the process is. On a 98GB volume with 427 fragmented files, the defragmenting process took under fifteen minutes to complete.

Command-line usage

Using UltraDefrag from the command line will seem second nature to those of you who have played around with other open source tools. The structure of the command is:

udefrag.exe OPTION

By default the executable is located in the system32 directory, so the command is global (it can be run from any directory in a terminal window or from the run dialog box). Here is a listing of the possible options:

  • a - Analyze a volume
  • o - Optimize file space by moving all files to the beginning of a drive
  • l - List volumes available for defragmenting (excluding removable drives)
  • la - List all volumes available for defragmenting
  • b - Use default color scheme

So the process of defragmenting a volume from the command line would look like this:

udefrag.exe -l
udefrag.exe -a C:
udefrag.exe -o C:

Scheduling

You can schedule defragmenting with UltraDefrag. To schedule a process, you need to open the simple scheduler too. To open this tool, click on the Start menu and then click on the UltraDefrag submenu. Within the UltraDefrag menu, you will see the Scheduler.NET entry, which will open the scheduler (Figure C).

Figure C

It doesn't get much easier than this to schedule a defragmenting service.

The scheduler requires you to set only the volume, the frequency, the time, and the day of the week. You cannot schedule a onetime defrag; you can only schedule recurring instances.

Creating a portable version

One of the best features of UltraDefrag is the ability to create a USB version of the tool. Once it is installed on the flash drive, you can take this around to any Windows machine and use UltraDefrag without having to install it on the machine.

It is quite easy to create a portable package. All you need to do is place all the files in: Start | Programs | UltraDefrag | Portable package onto your USB drive. You can optionally set some configurations for your Portable Package by using a configuration file named PORTABLE.X. With this file, you can configure where to show the bootsplash image and the language. Here's an example of the contents of the file:

[Bootsplash]
Show=1
[il8n]
Language=English

This file is placed on your USB drive along with the rest of the contents of Portable package.

Final thoughts

If you use a defragmenter to keep your Windows machines working at their optimum performance, it would behoove you to take advantage of UltraDefrag. It's faster, lighter, and offers better features than most other, similar tools.

Hi -- I just wanted to pass this on -- When I used this, 1) It took over 2 hours to defrag a 40G with only 25% full AND 2) It garbled a dll and Froze me out of Win completely -- I had to get a dealer to re-install XP since I had the pc used and had no discs. POS in my opinion. Ed

Reminds me of windows 6.xx defragmenting utility. Almost & Exactly the same. You install Old Windows version on today's computer, or you install a DOS based utility. They are bound to run fast, so there's nothing special about it. Plus, I fairly doubt your computer will behave when giving defragementing command from the Command Prompt. Check it your self... you windows will go corrupt!

15 MINUTES!!! It took that long just to Analyze my 120G drive of which only 22G was in use. It then took more than 4 hours to do a Defrag. I then immediately deleted it from my system.

Does it support optimizing for Prefetch using information stored in layout.ini? Because, although PerfectDisk 2008 (the one I'm using now) is a commercial software, it *does* support optimizing based on layout.ini, making my boot time (and initial application load time) faster.

According to their instructions, in order to install on Vista, you have to disable both the UAC and driver signature verification. That's insane!

Can't run it on Windows 7 - doesn't like the fact that a driver isn't signed.

I hadn't looked at any other freeware solutions. I like Diskeeper for production systems where there is a budget for such things. I have used the commercial product on 2TB+ volumes with good results. (every now and then, it will continue running outside of its scheduled window, which causes performance problems) I am looking for an alternative to Windows' command line defragmenter so I can schedule the defrag once, and forget about it forever. I also like the idea of a portable defragmenter. That can be helpful on vendor supplied machines where I am prohibited from installing anything. Unfortunately, the command-line tools don't seem to be available on the portable app, so no scheduling is possible. I installed the full package and ran an optimization on my slow-as-dirt laptop. The job did take several hours, but I was able to use my laptop all day without any noticeable degradation in performance. I run a second instance of XP in a VM for my VPN, e-mail, IM, etc., and have used remote support tools such as RDP, used various web based applications, and joined a WebEx conference without the slightest hint of a performance problem, even with the hard drive light blinking away. ...Can't do that with the Windows defragment utilities. The portable app did require me to copy udefrag-gui.exe & udefrag-gui-config.exe into the portable directory on my USB stick. Once those two files were there, I defragmented one of my VMs in a few minutes, while I continued to work. Again, no noticeable performance hit. I don't really care how long it takes if my apps still run well during the defrag.

Does anyone know how this compares to Defraggler? The latter is my freeware defrag tool of choice... [edit] oop. Nevermind. Looks like this has somewhat been talked about already. (and I feel foolish for having not noticed that thread...)

Most comments have described the speed at defragmenting of various tools. But which tool does the best job, resulting in the best OS performance once it is done?

It appears from the Ultra Defrag site, that you must disable the UAC to use on Vista. What really bugs me is their insistance that disabling the UAC poses no security risk. Is life easier without the UAC? Yes. But to say that turning off the UAC poses no security risks is just plain false. I clean up infected systems all the time. Infected XP machines (by the time the customer calls me) can take up to 3+ hours to fully clean the system, clean the registry and repair damaged or missing files. On Vista PCs where the UAC has been left active, infections are dramatically reduced and when they do get infected, the clean-ups generally take no more than an hour because the UAC limits the extent of the OS exposed to malware. Say what you like about the UAC being annoying, it does work. Also, on the signature issue that the Ultimate Defrag site demeans. I, personally, like the idea of having all drivers digitally signed. If Microsoft would also exercise this policy for all of their drivers, as well, systems could be even further protected from malware drivers posing as Microsoft drivers. If you want a secure system, some sacrifices have to be made. XP is versatile, but not near as secure as Vista. Vista is more secure but not as friendly to open source programs like Ultra Defrag. So let the User beware and pick his own poison. I will use Ultra Defrag on XP boxes, and I look forward to the day when they comply with Vista Security standards.

I tried UltraDefrag on an XP pc and it took much,much longer than JKdefrag. JK would have defragged both my hard drives in the time it took Ultra to analyse just one.

I can run the full isntall clean. I can run the binary in the portable directory on the test system. When I move the portable to another system it shows the splash screen but doesn't run any further than that. Test machine and secondary test are both 32bit so it's not the i386 breaking when run on 64bit. Boo.. hopefully I'm the only lucky one having this issue.

Off hand I would say some of you have some serious fragmentation. I notice that no one made a distinction between simple file defregmentation and optimisation. Defragmentation of a file just makes it continuous on the hard drive. Optimisation is on several levels. From moving of frequently used files to moving everything towards the outer edge of the disk, where the spin is faster.

redewenur

Anyone who has a compulsion to sit and watch a defragger do its stuff will probably reckon that speed is critical. Not my idea of entertainment, though. If the drives are defragged reasonably often, even relatively slow progs will get the job done while you visit the John or feed the dog. For me, any reliable bug free software will do. I've used Auslogics Bootspeed for about a year, and that's fine. Never timed it, hardly ever watched it, but the drives get defragged just the same.

While I have just read about Ultra, and not tried it, I have used Defraggler and surprised to read that it would be faster than Ultra.

Go to http://www.defraggler.com/download and download Defraggler. It supports 32/64bit systems, is portable, it defrags individual files, and is less than 1 mb in size and it is fast. Having read all the reviews, I would perhaps try Auslogic, but not waste time on UltraDefrag.

The only requirement I can see listed is .NET if you want to use the scheduler. My question will be how this stacks up against jkDefrag. It's screensaver mode is a nice touch though ultraDefrag at startup could work well for a machine rebooted frequently without much screensaver time. Real interest is in how they two optimize files for use.

damon.mac88

I do agree with other people who have commented on this software, its slow. And i would say its extremely slow at analysing th harddisk, ms defrag utility only takes few seconds to do it. And reading the article it says it uses a kernel mode driver, with such a low level access i wonder why its so slow.

gorman.mi

I think a lot of people have forgotten about Defrag, and think it was a part of the old IT scene, I find that it is one of the cheapest and effective ways to improve PC/Server performance. Users who complain bitterly about how slow their PC is, after I run defrag marvel at the difference..

Does anyone know of the impacts of defragging a NTFS volume (c: drive or any drive formatted with NTFS) from the command line (like this program says it will do)? How does the program gain access? How does the executable work off the USB key? It says there is a portable option but does it require windows to run first? Is there a 32bit version or 64bit version?

I have been using Smart Defrag from Iobit for a while now on many machines. In addition to all the features mentioned in this article it has the ability to automatically defrag my systems when they are not in use based on my configuration settings! So how often = all the time when my computer is idle!

With 10+ years dealing with 5000+ workstations and servers and being in the past the Director of Operations on a hardware lab, I can for sure see this defrag is quick and nice. I normally use Raxco Perfect disk, Diskeeper Professional or Winternal Defrag Manager for servers and workstations. This new tool is quick, free and small. My actual volume (40gb of data) takes only 70 secs for analyzing and less than 10 minutes for the full defrag. This is just amazing. I need anyway to compare performance gain after defrag, where the winner normally is Raxco Perfect disk with the offline & folders defrag features. I defrag every 3 months in my preventive software maintenance. Thanks for this post, nice one...

I tried the UltraDefrag and I think it is quite slow. I use Golden Bow Systems VOPT defrag program and it is much faster and defrags better.

So far it has spent 15 minutes on just doing an 'Analyse' as they spell it. I would NOT recommend this product at all. I'll stick with what is built into Windows. It is FAR faster than this piece of crap. It is STILL counting how many files on my drive. I just stopped it and am starting an uninstall and then a Windows Restore. It simply does not work well. Sorry I wasted my time on this one.

I've just defragged my wife's laptop (runs a slow version of Vista!). It took 15 minutes and I've always thought Auslogic's Disk defrag is quick. Mind you, the disk is 120GB and 70% full with 180,000 files. 967 files were defragged. Whilst this program may lack some of the functionality of UltraDfrag, it's very small, installs in seconds and does the job without any hassle. Works for me.

JKDefrag has been updated to now be called MyDefrag. Unfortunately it seems it now needs to be installed rather than just running an .exe. Both products are small and fast. I ran JKDefrag on an old laptop that had never been defragged. Bootup time went from 90 seconds to 45 seconds. R.

No. According to the UD site, you must have the UAC turned off to install and RUN Ultra Defrag.

I'm a skeptic on optimisation of frequently used files. If the frequency with which you use various files changes over time, then the software will be forever rearranging them and thrashing the drive unnecessarily. To me, the best thing about a defrag is that it can reduce the workload of the HD. Some attempts to optimise could make matters worse in that respect.

treborsnikwad
treborsnikwad

Defraggler works the fastest to me, and I've tried several during the years...I don't sit and watch the defrag operation exclusively, but it seems to run in the background unobstrusively, and the task is completed relatively quick.

Neon Samurai

I flipped a test machine back and forth a few times. UltraDefrag consistently took longer to redo it's own work or optimize the jkDefrag optimization. jkDefrag consistantly managed to reoptimize the UltraDefrag optimized scatter much faster. This testing wasn't measured scientifically so UltraDefrag's optimization may be more efficient for some but it didn't feel that way for me. Meh.. it's just defrag and fast drives today don't actually benefit enough to put a week of research into it. I'll stick with jkDefrag as a screensaver on the few machines that need the special attention.

twistedg

Smart Defrag scanned my 120 GB hd with hundreds of fragmented files in two seconds. Reported a complete defrag in less than one second. MS defrag showed no change and files still fragmented. Further Smart Defrag scans didn't even scan; just immediately popped up same results.

HelpDeskGuy
HelpDeskGuy

Agree with balford...all the bells and whistle of the others (small footprint, scheduling, etc.), but love the fact when I leave my PC for a while, defrag will kick in automatically (called Auto Defrag). So I am always defraged!! The only thing it doesn't do (I think) is defrag individual files....but why would I want to do that?? Especially since this will continuously defrag in the background...

DomerD
DomerD

I've read several replies. Some say it's fast. Others not. I ran it in analyze mode and it ran for hours! (Overnight) Then i tried it in defrag mode and it ran for hours again and apparently didn't do anything! What's up? I'm not sticking around to find out. I'm uninstalling.

I downloaded this Defragger based on the article and found that it is the worst Defragger I have ever used. I have a 150 GB harddrive and I only filled 40 GB of it. After 45 minutes the Analyze was at 96% and not going beyound that. I stopped it and removed this piece of junk.

This must be the SLOWEST defrag utility I have ever come across! So slow in fact, that the Microsoft Defragmentation utility is far, far faster. There is a defrag utility included with Tune-Utilities 2009 and that is also far faster. How this product ever got on TechRepublic as a 'fast' defragger is beyond me! As I write this post the 160Gb drive I have with 55% free space is STILL compacting after 3 HOURS! UPDATE: I made the above post 2 hours ago and had to stop UltraDefrag. When I ran Microsoft Disk Defragmenter, the hard disk WAS MORE FRAGMENTED than when I started!!!! If my disk is damaged I will be suing.

denkile

I have used UltraDefrag for a year after doing the trials on the full defragers: PerfectDisk, O&O, Diskeeper. UltraDefrag "compact" is faster but must be run in an idle OS with apps and security OFF. It has a very good boot defrag for the OS files. It takes longer to analize than to defrag. I run UltraDefrag "boot time" at every daily startup followed by XP Defragment. 'Monthly do the "compact" which takes an hour and Ver 3.0 effectively rearranges the disk The other full defrags (above) take longer to rearrange and compact. The daily boot and monthly compact improve performance more than Registry Repair.

alexisgarcia72
alexisgarcia72

This product is not slow. In my pc with 2714 fragmented files, a 40GB volume takes 70 secs for the Analyze function. The full defrag takes only 9.45 minutes. This is an amazing speed, I just need to review the defrag performance achieved because I normally use Raxco Perfect disk, Diskeeper Professional or Winternal Defrag Manager and this softwares not only perform a regular defrag but organize file location based on use and file importance.

TheOnlyRick

It's not very surprising that someone chooses to spell 'analyse' with an S instead of a Z, is it? You do know that is just the British, Irish and Commonwealth countries' spelling (like colour, traveller and aeroplane)? R.

Used the old 3.3 of JKDefrag and it's nice and portable. Since the author says nothing gets dumped elsewhere in the system [and if you don't care about the scripting part] you could in theory make it portable as well Note that the installer installs either the 32-bit version or 64-bit version, depending on the bit vfersion of Windows. So if you have Vista 64bit and you want the 32-bit version, you'll have to install it elsewhere.

I have used this defrag utility on several machines without problems. Also, it is much faster than the Windows defragmenter. The fast optimize is a good feature, but have not tried the deep optimize yet. I had an older machine with Win XP that was messed up after running a defrag on it using the Windows defragmenter.

john.mackechnie

The defrag took over 12 hours to run on a 50GB HDD with 20GB free on a disk that had been defraged 6 weeks ago. The best bit is I ran the Ultradefrag analyse the next day and it shows a fairly badly fragmented disk, so I ran the windows analyse and that too shows quite a badly fragmented drive, what the????? Tech republic need to research a little more before proudly posting these items and emailing them off!

I am the writer of the article. My experience with this tool was very positive. I have used this tool on a number of different disks, in a number of sizes (and states of fragmentation) and have found it, every time, to be faster and more reliable than the Windows defrag software. I have not experienced any of the claims the unhappy users have had.

Reinforcing DataCommGuy's post, I tried Ultra, and it IS slow. I deinstalled it & will revert back to MS and Defraggler.

Neon Samurai

A: analyst the drive D: defragment the files C: compact the files A and D are pretty strait forward. For C, it copies the files to the back of the drive platter then copies them all too the front in an optimized order. I was looking at a Defarg during boot with a regularly scheduled Compact to clean the drive. Still, always good to hear about more software options and UltraDefrag may fit someone's needs perfectly even if it didn't fit my own.

carl.frank.wilson
carl.frank.wilson

No I did not stop it in the middle - after 3 hours of churning, apparently fragmenting files randomly that were not fragmented, the progress bar reached 100%. THEN it started another one from 0%. THAT'S when I stopped it and went over to good ole faithful Disk Defragmenter, the OS one. I took care to end the program by pressing the STOP button (by the way the programmer thinks there is no difference between PAUSE and STOP) and not using TaskManager (hoho) so that files were not left open etc. and after 40 minutes disk was tip-top.

Datacommguy

If you'd taken a minute to browse their web site's FAQ and Help forum, you'd have seen a waving red flag after reading many complaints of extremely slow operation (or aborts). The 'official' answer to at least one claimed that the speed of any defragger is dependent on available free space, number and size of fragmented files etc (Duh) but several blog entries also mentioned that the standard Windows defrag program cleaned their HDD up in a relatively short time (with log files to prove their point) after this program has spun it's wheels for "ages" and was only 20% - 50% done. Bottom line here, I think, is that we've all seen advertised products that don't live up to their marketing claims. But... how did this one make it into a glowing TechRepublic recommendaton?????

tr

So you stopped the utility in the middle of its operation and expect it to be completed...

OK so I will sue TechRepublic for recommending it to me. As for paying for a piece of software that leaves your drives more fragmented than when you started - how much could they charge you for that?

kenmo

Suing who? First read the license agreement... And if you don't have a recent backup, you should not be running utilities with the potential of messing up your drive (as all defrag utilities do).

Analyse may be acceptable but the authors are clearly not British. In fact, in a fit of inconsistency, there are at least two instances where analyze or analyse is spelled with a Z. Every page except The UltraDefrag Handbook (main page), Reporting bugs and Credits and License is riddled with grammatical and spelling errors. NOTE: Edited to remove my quotes as apparently TechRepublic cannot insert them properly. :)

I have been using O&O 2K for years and it works great and is very fast! It uses the Space method of defragging. I also use Diskeeper Ver:8.0.459(not free) but, only for a special feature it contains! Diskeeper is the company that makes Microsoft's basic defragger. Diskeeper does a good job of regular defrag and can be set to run in background continuosly defragging. But it is extremely slow so I don't use either function but it has this feature that will upon rebooting will put all the folders on a drive/partition at the beginning of the disc! The first time I tried it I could not believe how much faster my PC searched and operated in general! I Defrag with O&O first then do the Boot time defrag to put folders at beggining only with Diskeeper and yer done! I do the Boot Time defrag once or twice a month and use O&O weekly at least! Here is a few URL's for downloading O&O 2K if anyone is interested,, Good Luck: http://majorgeeks.com/O&O_Defrag_2000_Freeware_Edition_d4545.html http://www.filehippo.com/download_oo_defrag/

The only thing that the installation of MyDefrag does, is associate the script extension of MyD with the program. You can install the program on your computer, then copy the files to a USB stick, and run the program on any computer. I created a one-line batch file on my USB stick to invoke the executable with the name of a script that I wanted to use, and it works great.
