Randy User There are many defrag utilities on the market, many of them free, but IObit's product is one of the fastest ones I've used - there is a good video tutorial at the MajorGeeks download site, showing how to configure SmartDefrag v5, including how to set it to delete junk files before optimizing your disk.
Aug 5 2016 at 6:32am Copy Link
Serious Noize Using Windows 10 Anniversary Edition. I am curious, I use Windows 10 Built in defrag with the /W on command line on a task schedule, which means it gives Window 10 built in defrag the command to defrag or Consolodate all files on the hard drive regardless of size, meaning no 64MB Limit, and it defrags by ZONE.

So could someone please explain to me if I were to use Smart Defrag how it could possibly do a better Job and or would there be significant speed differences?

For one thing, I've tried many in the past, even SD but that was on an older PC and a long time ago. Not to mention, why would Windows Defrag using the /W as I am not be the best option? After all, it is SAFE first off, and secondly, with Smart Defrag or SD as I called it earlier, benchmark test are inconclusive, they cover a specific PC and not all of them, probably OLDER ONES, I have a brand new PC and the latest Windows 10 Anniversary windows version. So I ask you? Please explain to me how this can possibly be better than Windows Defrag using the /W command in a task schedule when needed?

Thanks in advance.......

Randy User @Serious Noize: if you have a new PC with a fast hard drive you might not notice much difference; but I can tell you, the built in Windows Defragmenter is not highly regarded. And you can't set it to DELETE the myriads of temporary & junk files before optimizing your disk, the way you can with programs like Smart Defrag. When you click 'defrag' in Smart Defrag, it analyzes your file system, then chooses the appropriate optimization scheme automatically. And of course you can schedule it to run anytime you like; you can also set the 'Auto-Defrag' feature to examine your disk during low CPU usage and defragment when it needs it; etc. Most any of these 3rd party tools are better than the built in Windows Defragmenter, IMHO.
Aug 5 2016 at 2:49pm Copy Link
Serious Noize @Randy User, Thank you, I already use CCleaner with CCleaner enhancer settings to clear most of that stuff. Although a few things you said about the product I really like. The auto defrag option sounds very interesting. I do wonder about the 12 month trial.

I mean, if it works as advertised now and I turn off updates "If I can that is" will it be free to use forever? And or does this offer mean I will get updates for 12 months and afterwards it will turn into the free version only meaning lacking in several functions?

Or if I use this 11 months getting all the updates, and turn off "UPDATES" will it still remain a pro version?

I guess this is a question for IOBIT and not you Randy, but thank you for taking the time to reply and answer, I really do appreciate the information.
Aug 5 2016 at 2:56pm Copy Link
Bill Sech This is the Pro version as opposed to the "Free" version. I am using it and have used the free version in the past. I like it. Seems to work good.
Aug 6 2016 at 9:05am Copy Link
Randy User @Serious Noize - IObit products are on a 12-month Subscription Model, so after a year you can choose to renew the software subscription for another year, or let it revert back to the 'free' rather than 'pro' version. That is up to you: IObit periodically offers discounts to those who are already their customers. This utility doesn't cost that much if you deem it worth renewing a subscription.
Aug 6 2016 at 11:16am Copy Link
Jim Stone I'm sorry but there's simply no good reason (other than greed on the developer's part) for something like a defrag utility to be using a subscription model.
Aug 6 2016 at 1:01pm Copy Link
Bill Sech In this deal, they've suspended their money interests for a year. You get to use it for a year free of charge. Don't want it after that then you can uninstall. They do not ask for your credit card or anything like that.
Aug 6 2016 at 2:09pm Copy Link
Randy User @Jim Stone - Auslogics DiskDefrag Professional does the same thing - not sure but I believe the 'Pro' version of Piriform Defraggler is similar. For existing customers of IObit, they can renew a 1-yr license for five bucks or so. As Bill Sech posted, this is a freebie and no need to renew if the user does not wish to. IObit uses the subscription model for all their products, and offers substantial discounts on subscriptions to those already their customers.

njf I have just installed it. Unfortunately, it does not scale well on 2160p/4k screens. I find it almost impossible to read the print in the settings etc. I hope there is a way round this, otherwise I may just have to uninstall it.

William W. Geertsema @Norman Fisher
I also consider the GUI, with its default settings, almost illegible. I did the following:
I managed to make it barely legible by changing transparency:
1) At top left of main screen, find and click on "Options"
2) Select the top item of the drop-down menu: "Settings"
3) Click on "User Interface"
4) Slide the "Transparency" slider to about 3/4
5) Click on blue "OK" button at bottom.
This makes the GUI barely legible.
Maybe this is of some use to you!

Two additional remarks:
a) When confronted with such almost illegible GUI's, I take a SnagIt snapshot of the screen in question (generally first the opening screen of the program, and as a JPG image), open that with IrfanView, and then adjust brightness and contrast until I can discern the legends etc. Then, when I put that image on my display next to the program's screen, I know where to select a choice or hit a button.
b) I fail to understand why many developers (especially in the last two years) assume that everyone has bought the most recent hardware, has perfect eyesight, and looks at his/her display in a dark cubicle. This smacks of youthful arrogance, and some contempt of older (and often much more experienced and savvy) users. The more so since it is a small matter to code a choice of several GUI themes (color, brilliance) into a program. I may add that I believe that many very experienced computer users (especially those that use a computer to compute and for other serious purposes, instead of to play games) are loath to buy new hardware, as long as their existing machine does the job adequately.

Sputnik Independently from the software we are talking about, the rentalware model is a nonsense for all softwares which are able to run by themselves at the opposite of a lot of security softwares which need constant malware signatures updates.

This is the case with IObit Smart Defrag which can run by itself without the need of constant signature updates.

In all the cases where you are facing a rentalware software, you should look for freeware versions or paid solutions that you may use indefinitely past the free updates period.

Finally, concerning which is the best defragmenter, there are a lot of tests which have been made, the best ones being always those who are based on a thorough analysis.

After a very fast Google search I have found these two ones :

Personally I use Puran Defrag, which is free, because we may define automatic defragmentation plans.

I just run Puran Defrag with such an automatic defragmentation plan. I just have nothing to do and the fragmentation rate on the hard disks defragmented by Puran Defrag is always at 0%.

SoftCollector For most purposes defragging is dead. SSD's should not be defragged, or you risk shortening their life span. HDD's can be defragged, but should they? It has always been more smoke and mirrors that true advantages. In recent years many of the former big names in the business have exited.
Mar 22 2017 at 12:57am Copy Link
Rheal Poirier Nice reminder. Yes, I agree with your point. But more and more SSD drives are performing and their lifespan increasingly improved. So I believe that occasional defragmentation becomes a plus just like the one that HDD. The opinions are divided on this subject but I believe that there should be only defragmentation of a SSD disk if there are starts of misfire or slowdown in the transfer of the data ... But it can take many years for the " Normal user of a computer. Everything becomes so relative in these things. ...
Mar 23 2017 at 7:37am Copy Link
STEVE K Your response to Paul Williams is not an answer, just an ad for the Pro version he is askikng about! Your Screenshot button shows this offer as the Free version, which has no time limit. Why, then, do you place a 12 month use restriction on it?
Also, since today is Thursday, 3/23/17, why does his question, & your response, say Tuesday?
Mar 23 2017 at 7:44am Copy Link
Thor Johnson Why would you want to defrag a SSD? You don't even know what it looks like on the inside (it looks like a "normal disk" because of the SandForce or other controller chip -- and that chip handles partial erasures, bad block mapping and all the other esotericness).

The only thing beneficial to SSDs is the support of the TRIM method (where the OS can say "these blocks are no longer used, so don't preserve them"... if you don't have the TRIM method, the only way to tell the SSD things are unused is to write (I think 0's, but in-the-flash-chip, it would be 0xFF) to all the unused blocks, but that does put some extra wear on the chip (but you get speed back -- it takes less than half the time to change 0xFF->any byte than it takes to change any byte to any bite [programming more 0's is easy. otherwise, you gotta erase to 0xFF and program what you want]). But "Writing Unused Blocks" is iffy and really depends on the interface chip understanding what you want (why they made the TRIM method so that it's actually a standard).
Mar 23 2017 at 8:13am Copy Link
Techfixes Actually this is a very good program. I have already used the Free version and it will be nice to try out the Pro version.

This is definitely one of the more full-featured Defragmenters out there. It is far more capable to the one built in to Windows.

Regarding SSD's, I don't see any reason not to defragment an SSD occasionally.

Ed User Steve K I'm with you. People who beat around the bush usually have something to hide - and they're not always politicians. The iObit reply - as inconclusive as it was - is not as baffling as Paul Watkins complete change of tack and comment that he "doesn't see any reason not to defragment an SSD occasionally", especially in light of comments by Rheal Poirier. and Thor Johnson above.
I may not see any reason for many things, but stating it surely contributes nothing.

Russ L There are no moving parts in an SSD drive, so I don't see any reason to defrag it. The reason you defrag a drive is so that a file is physically located all in one place on a hard drive, otherwise the older non SSD drives may have to physically "seek" multiple different areas of the drive platter to retrieve a file thus slowing down access.
Mar 24 2017 at 9:56am Copy Link

Constantin Florea @Pi Stachio, Yes it is. Since the only paid license on the product website is the Pro license, then this is the Pro license.

We can only promote products or product licenses which are sold for a price on the product website. We cannot present or promote products which are already free on the product website. The reason for this is because if we were to do this (if we were to promote already free products), then there would be no incentive for our customers to go through our checkout purchase flow, they could simply go to the product website to get the free version from there.
