Defraggler Pro Key

[Cecila Dammrich]

I'm currently using defraggler free 2.22.995 (64-bit) and it has some problems with my 8TB external hard drive. I tried several times to start a defrag, but everytime it stops when it's not finished yet, and it seems after another analysis that it's more fragmented with a lot more space tagged as fragmented.

If I go to File list, I can see the list of files that a fragmented (as expected), but when I check one and try to defrag this one specifically, it says "Defrag aborted. No files were defragmented. The operation cannot be done.".

Do an Analyze and then View Files, select all the fragmented files (checkbox at the top selects them all) and then 'Defrag Checked'.
That will defrag the fragmented files without trying to move everything about the drive to save space, so it will be a lot quicker.
(Let's face it with an 8TB drive you shouldn't be short of space).

The 'Defrag Aborted' message is displayed when a file has been re-opened/changed since the analyze, in that case it would not be safe to try and defrag that file using the analyzed information. The longer it has been since the analyze the more likely it is that one or more of the files has been changed.
All other files will have been defragged as expected, only those that have been reopened/changed will have been aborted.
Analyzing and defragging the files again should do those if needed.

I used to get that message quite a lot (every time almost) when defragging the file list and it was usually Windows Defender files, although sometimes other system files.
It doesn't seem to happen to me much now, improvements in Win 10 or in Defender?

Close the message and look at the filelist, you will see that most files listed have been defragmented (now only one fragment), those with more than one fragment will be the ones that couldn't be and you will be able to see just what those are.

TBH that "Defrag aborted" has always seemed a bit too harsh a message to me, and it's incorrect when it says 'No files have been defragmented. ('Defrag incomplete' may be better).
It gives the impression that nothing has been defragged when in fact most stuff has been and it's only a few files that haven't.
I think the message may be a hold-over from the early days of defraggler which should have been changed but hasn't.
Just one of the many wordings/messages that needs an update.

So, it did not work well....some files were fixed, but I still have files that are fragmented (though the number drastically decreased). The fun part is, on the other drive I don't have problems to defrag them. So I think it's this drive, and I think it's the file system, because there isn't any problem on the other drive (4TB) and it's NTFS...

That post you link is 11 years old and talking about Vista/XP, as far as I know Defreggler should now be able to handle exFAT (at least that is what the documentation says, I've never had reason to try it myself).

It may well be that with your large video filesizes there is simply not enough free space to temporarily move enough files into.
I don't know for sure, I have no idea of how defraggler moves files about, or how many it moves at once.

Which is why moving some to a different drive worked, in effect you were doing the job manually and the second drive increased the free space you had to work with.
(I don't know of a defragmentation tool that could use a second drive for temporary storage, but there may be one somewhere?)

You assume well. So I guess I can't get better, but anyway, thank you. Do you know a section to submit ideas ? (the one that defraggler could use a second drive as temporary storage). I think it could speed up the process, because reading/writing speed is a lot affected when it on the same drive.

I tried using other software before and PerfectDisk has the same issue but it then marks the status as "Unmovable". None of the alternatives help. Almost makes me want to switch to NTFS even though I dislike the format.

I have many big MKV files and the total drive is 15% fragmented. Because I hardly ever touch the files I want them all in a nice bulk at the start of the drive for further additions later. If this is a bug with exFat then I suppose none of the software can ever do it?

Hi all I am first time using defraggler. My laptop is only used 3 months it . I recently decided to Defrag with defraggler software for the first time defrag and it's took too long. My Hardrive is partition to c and d. My c drive is only 99gb and d is 360gb.yesterday I Defrag c it took long and I have work to do with pc so I cancle it. Today I have free time and Defrag d drive it say 6%fragments and It took over 8 hours to finish it. Is this normal. I am afraid of of Defrag of disk c. C have 25%fragments. How long can total take to Defrag c25%fragments. My laptop spec are i76700hq, ram 12gb ddr3l, WD 500gb 5400rpm,gtx950m window 10 64bit.

let DF analyse your drive then go to the File List tab, sort the Size column by descending order, select the top 100 or all the files greater than 50K (whatever rocks your boat), right click those and select Defrag Highlighted.

I did as you said to disk c and than it fast and stop around 67%and said this file can't move defragment abort. When I analyze again it's around 23% fragments only 2%fragments reduced. Yesterday I Defrag my drive d and restart my computer my c drive space become low from 12gb to 6 gb I deleted some files and it low again from 6gb to 4gb.today I opened pc drive c become 4gb to 11gb. I thought my drive is something worg after defragment. Before defragment my drive don't have like this. Aftert Defrag my drive d benchmark said 1.5mbs.i tried to copying something to drive d and the write speed is also around 30mbs.before Defrag it's up to 80mbs.is defraging make my hdd worse? Do I really need to Defrag disk c after defraging disk d. If I don't Defrag c what is consequences. Both c and d are same drive with partition.

Andavari, there hasn't been an MS Windows OS that hasn't included a defrag. The early Windows OS defragger was written by Executive Software, which is now Condusiv.
So, you'd be wrong when you stated to FullMetal with..." OSes like Win10 automatically defragment on there own".

I see this all the time in Forums. Forum Members replying to other Forum Members who are looking for help, making statements as if they are correct answers... that in fact, are incorrect... and without any referencable info to support their assertions. The issue is lack of research. People see a blurb and take it as gospel, when in fact they should always verify all infomation put forth. And it's simple enough to do!

Note: MCSE was the acronym for Microsoft Certified System Engineer. We were straight up Systems Engineers that implemented and administered the Windows NT Architecture. MCSE is now the acronym for Microsoft Certified Solutions Expert.

... Windows 10, like Windows 8 and Windows 7 before it, automatically defragments files for you on a schedule (by default, once a week).
... So with SSDs, just let Windows do its thing and don't worry about defragmentation.

I didn't notice the date of the original post before I commented. Still though I think it's worth noting that Andavari was correct. Unless of course I have managed to completely miss the point of yet another post.

I've the same problem. Started to defrag my Toshiba P300 3TB (99% fragmented files) this morning and it's running 6,5 hours now and the progress is on 25% I see on the map that blocks are moving and changing colors between yellow and green. Files on this drive are big ones, definitely more than +20GB per file as this hard drive is just for Acronis True Image backup images. So annoying it takes sooo long time. All your solutions from this thread has been applied before I've started to defrag this drive. Is it because of the amount of fragmented files and the capacity of this hard drive? Is it normal? Would the time to defrag decrease if the partition was for example just 1TB? Thank you in advance.

Why not just run an Analyze, and then in the file list only defragment files which are fragmented. It goes allot faster doing it that way instead of letting it take forever doing a full consolidation/optimization/fill gaps as some other defrag tools would call it. Then you could either wait for Windows own built in optimization and defrag to run, or manually invoke it if you haven't set Defraggler as the system default defrag tool - that way it won't clash with Windows optimization and defrag.

Should I check all files in the file list or just some of them? Can these files be checked automatically then, right after analyze? I've set Defraggler to automatically defrag all my HDDs whenever they reach 30-60% (depends on disk) once a month so defragmentation isn't anything I'm doing manually.

You stated the drive contains your Acronis disk image backups, from my experience if it's a data only drive with no OS installed onto it with the main purpose being to only make backups you end up wasting allot of your time allowing any third party defrag tool to fully optimize it - unless of course you place a file size limit on what it can and cannot move. Hence the reason I mentioned only defragmenting what's listed in the File List. Windows own built-in optimize and defrag will then attempt to consolidate/optimize/fill gaps on the drive (if scheduled to do so, but it's good to manually invoke it when you want it to run) so you have larger areas of free space, however with Win10 it will only bother with files that are 64MB (yes megabytes) in size or smaller.

As for defragmenting disk image backups it's important to take into consideration that defragmenting them doesn't really give you a performance boost and how big in file size the disk images are takes a long time to defragment them. For instance if I had a 50GB disk image backup with 20 fragments I wouldn't waste one second of my time defragmenting it since those fragments would be 2.5GB in size each, and I especially wouldn't defragment it if it were going to be a "throw away" disk image I'd be replacing with a new one within a 3 month period. I know it's a 180 degree shift in thinking on how to defragment (or how we were taught to do it) however it doesn't unnecessarily waste your time or put hours of stress onto a backup drive.
