Hi Piriform,

another low priority suggestion would be to not rely on users having a specific internet browser like internet explorer.

When I click on "help" and "about" there are links like "www.defraggler.com" or "www.piriform.com".

Now, for security reasons I have IE generally disabled and use firefox instead. ,When I click on your links, nothing happens even though my mouse changes its' looking when I hovver over your links.

It would be nice if clicking on your links would open a new tab on my browser window.
Or when I get informed that a new version of your software is available for download, I'd also like a seperate window tab in my browser to open up.

Thanks for your great software.

Regards

When I click on the links, it opens a new FF tab...Same thing for updates...

I have started a thread "Number of free space fragments" in the general discussion.
It is really a suggestion that this statistic be obtained and displayed,
so this is a marker for it here.

[size="4"][/size]I have a PC with multiple hard drives and partitions
Would be nice to select all disks or partitions and to defragment one after another and then take advantage of the automatic shutdown.

Well I just tried again and in my german version of defraggler, nothing happens when I click on those links.
I have disabled IE to access the web through my firewall.

Don't know the cause.

Regards,

linux4all

Please add an option to prevent the computer from entering standby when defragmenting.
If this is already a hidden feature of Defraggler, it does not work on my computer, which is running Windows 7 RC x86.
Thank you.

I`d like to see such functions as
- ask before close program
- send to tray
Thank you

I'd like to see "average fragment size" in the file list.

That way I can choose to defrag only those files for which the fragment size is under the size of my choice. After all, a 100MB file with 5000 fragments is much slower to read than a 10MB file with only 3 fragments.

Another suggestion:
Support for SSD drives, preferrably automatic
The reason for this is that on an SSD it's ok to leave a few fragments in large files, and it's pretty much useless to move contiguous files around at all, since SSD's don't have disk-heads to move, and more importantly, SSD's have a wear-levelling algorithm which makes the drive "fragmented" internally anyway. Therefor defragging the FS is only good for reducing the already miniscule seektimes and lowering CPU load a little from heavily fragmented files.

Also, and this may be the greatest performance gean for SSD's: would it be possible for Defraggler to send the TRIM command to a disk for each piece of freespace? That way, an SSD would optimize it's wear-levelling and reduce performance degradation. Atm, only the OCZ Vertex supports this (and perhaps the Intel X25-M, not sure though), but I'm sure more will follow.

Number of Free Space Fragments
****************************

I suggest that this is by far the most useful statistic in defragmentation.
It is not displayed at all in Defraggler.

I have started a thread in the general area to discuss this.
Please, if you are a developer, just acknowledge that you have seen it.

First of all thanks for the most thorough defrag tool I have ever used. I have a few suggestions they are:

- add 'defrag all' button/context menu that does a normal defrag + free space defrag
- add 'defrag fragmented files only' button/context menu which would be a one click for analyzing + checking all in file list + pressing defrag checked
- add 'defrag free space' button of the function already in context menu
- +1 allow for multiple drives to be analyzed/defragged by selection in top frame
- +1 while processing don't lock top frame selection, so other drives can be processed at the same time
- during single file defrag remove the window that pops up and put it on the status page (drive page) instead
- remove redundant status (analyzing\defrag %) in the bottom pane since it's in the top pane already
- add to schedule settings type of defrag to perform: full, file only, free space only, fragmented files only
- add to schedule settings drive selection check box to select multiple drives
- add to schedule settings defrag drives simultaneously or sequential (one after another)
- +1 to defrag after idle for so many minutes option
- +1 to minimize to system tray option
- option to clean with ccleaner /AUTO before defragging
- +1 for showing free space fragment count \ percentage
- +1 for adding offline defrag of system files (pagefile, hiberfile, metadate, etc)
- show count \ percentage of fragmented system files

Considerations/Additions of any of these would be greatly appreciated.

Also while more of a bug report then a suggestion I notice the process priority (normal/background) isn't saved between program restarts.

As "crzftx" mentions previously, the Defrag Free Space seems a little backward. Obviously there is little information presented as to what is occuring but from the lovely squares it appears to start at the beginning of the drive and fill in the first gap with the _next_ available fragmented piece of data. The gap left behind by that piece of fragmented data may very well then be filled in by the following available fragmented piece of data, repeat until the end of the data is reached. What appears more logical is to find the first gap on the drive and fill it with the last available fragmented piece of data, thereby making (potentially) large gaps at the end of the drive available to defrag the largest of the files into.

Some new suggestions:

Create a new feature that shows the total amount of time it took to complete a defrag ("Defrag completed in time"):


Create a new "Auto Defrag" button and option that will automatically defrag all local disks without any more user interaction, and an /AUTOSHOWGUI switch to have it completely automated and show the program, and an /AUTONOGUI switch for it to be minimized in the SysTray or taskbar:

The Search-feature seems to work not too well in v1.10. I have 3 files which contain "mish" but the Search function found two files and the program failed to find the third file.

I do not know if this has suggested in the past, but, if there is an option to move large files towards the end of the drive, why not one for moving certain files (by either size or type) towards the beginning of the drive.

An option to ignore (not move) already defragmented files would be extremely good as well.

It might be tough to implement, but if the program "defragmented" on memory first to make all the decisions of where to move the files, it could then avoid what several versions do; move the same file a few times whilst defragging. I have noticed it as a big problem mainly when defragmenting the whole drive, as it will keep on trying to find space for those large files now kept at the end which have not been able to be defragged.

Am using Piriform Defraggler version 1.11.148 and it seems fine with me except for the speed of de-fragmenting. I would appreciate if it were a bit faster. In addition, its better if it could be minimized to tray and continue de-fragmenting in the background as I work. I pressed the Close button hoping that it will be minimized

Hello, there is only one actual problem that I can see in the entire program... There is no functionality to manually move items of a certain block to another block... I am having problems defragmenting a 200GB file because there is one file around 160GB from the end of the drive that is not fragmented and won't move closer to the beginning of the drive for any reason. I want implementation of the ability to drag and drop blocks/files to other blocks.

Number of Free Space Fragments
~~~~~~~~~~~~~~~~~~~~~~

Hey, developer guys, I'm disappointed that you haven't put this in the latest version.

(see thread of this title)

If the built-in Vista defragger can do it, why can't you?

It would be very nice if Defraggler had an offline-defrag option. In that case, ALL files could be defragged, including the pagefile.
I know PageDefrag: http://technet.microsoft.com/en-us/sysinte...s/bb897426.aspx , already does that, but it doesn't seem to work (very well) on Windows Vista.

Actually, the safest handling of a pagefile is to give it it's own tiny partition - preferably on your backup harddrive instead of your system drive, so it isn't competing for read/write time with day to day work - then set the start size and maximum size both equal to the maximum size, and have the contents deleted at shutdown for safety (which I do once a day - when I shut down at night). Voila! it's defragged every day.

You shouldn't defrag temp files - you should run CCleaner (and any other cleaning/optimizing you normally do as maintenance) before you defrag. The pagefile should be in it's own tiny partition & cleared when you shutdown for the night. You can also turn hibernation off, giving up the hibersys file before defragging, if you wish. Although some disk-oriented applications ignore the pagefile and hibersys file - this one may too, I don't know - moderators??.

I think it would be great if it didn't use so much of my systems resources...


MS Disk Defrag takes 50 ~ 100MB's
Auslogics Defrag takes 100 ~ 150MB's
Defraggler Defrag takes 1.2 ~ 1.6GB's

I think in terms of the best defragger per MB Auslogic is the best UI because it gives Verbose info on what its doing....

Performance wise MS Defrag is the best.

Options wise Defraggler...

I think you need to look at and optimize your code a bit and better verbose info and logging...

I have version v1.10 installed. I think v1.11 just simply ""sucks"". Although that version has an improved ""large fragments defraggler"" capability, I de-installed this version and re-installed v1.10. The reason I dislike v1.11 is the same as why I disliked v1.08 and v1.09 but liked v1.07. See my comments on this particular topic in this thread.

Not everybody would want to have to make a seperate partition for the pagefile. Sometimes it can be handy to just defrag the existing one.
Also, it's not just the pagefile wich cannot be defragged while running Windows. There's more stuff that qualifies for that, including the Windows Registry.

Today I have installed the latest version (v1.12) and must say I that do like this version better than v1.11 and I therefore have switched from v1.10 to v1.12.

In this version there's still a bug. I live in the Netherlands and I therefore use the dutch language version of this program. In the column "Fragmentation" the english word "Unknown" in the dutch language version isn't replaced by the proper dutch word ("Onbekend"). This is clearly a programming error because in the column "File System" the english word "Unknown" in the dutch language version is properly replaced by the dutch word "Onbekend". And this bug doesn't occur in the dutch version only but it occurs in every language version. That particular word "Unknown" isn't "translated"/replaced the moment one switches to another language.

I hope its clear what I am refering to because this bug already existed in version v1.10 and isn't/wasn't fixed in versions v1.11 and v1.12.

I came across something odd.
I use the option "Defrag freespace" (very) regular. I noticed that this function (always ??) skips files that are fragmented. I have made a picture of the situation (see attachment). There was a file in 10 fragments (in bright green and bright red). When I used the "Defrag freespace" option the last fragment of that file (in bright green) remained where it was placed. It looks like it could have been moved closer to the last files. (The new place were this fragment (in bright green) could have been moved to is marked by the black squares). This would have reduced the number of freespace-fragments and that's precisely what the option "Defrag freespace" is supposed to do. On top of that one would expect that this function would fill more free fragments/free space(s), that it would fill more "gaps".

Keep in mind: I am talking about the "Defrag freespace" option, not the "Defrag freespace (allow fragmentation)" option.

I think 'Defrag by Creation date' 'Defrag by Modified Data' 'Defrag by Name' and 'defrag by size' options would greatly benefit Defraggler

Also I would like a better looking UI, I am willing to make the UI images?

In addition to that I suggest adding a 'Sweep Defrag' Option.
This option will send the first 5 clusters to the end of the disk, get the locations of the first fragmented file on the disk and put them into an array, then moves the clusteres of the fragmented file in order to the start, once 1 cluster is written, the 6th cluster is moved to the back of the drive then another cluster is written and another moved to the back of the drive.

This feature would be great for Heavily fragmented drives (Such as mine - 872GB 46% Fragmented) it would save time, however for low fragmented drives this feature would be highly ineffective.

Could be part of next Defraggler version an option to minimize the window to system tray?
That would make more sense with that option to run in Background.

Thanks in advance!!!

Could the "Defrag Freespace" & "Defrag Freespace (Allow fragmentation)" options be added to the command-line version please.

From an administrative point of view, I'd like to see some logging besides that created by the /debug option. If there was some way (specifically using df.exe, but in the GUI version it would be appreciated as well) to throw out a -v option or a /log option so I could have, at the very least some "Fragmentation Before" and "Fragmentation After" stats generated, I would be most appreciative.

I've tried using Windows Defrag.exe to do this but defrag -a -v is limited in its scope. For example, defrag -a -v gives me a 9% fragmented stat on a disk where most of the file sizes for about 30 odd files range from 40MB to 100GB backup images. Defraggler on the other hand tells me I have over 60% fragmentation on the same drive.

Even if there was a "log" switch that output similar text to defrag -a -v but with Defraggler's accuracy that would be excellent.

I am sure this has all been suggested before and I apologize for this discretion should it exist.

Cheers,
Eric.

amen!
Status Properties Legend

just like that!
please!

I like the File Exclude option, but it needs a *little* tweaking.

1) If you select the file to defrag it from the file list, you should still be able to defrag it. Maybe a warning?

2) When you have a file extension in the list of files to move to the end of the drive, after defragging that file from the file list, it should move it to the end of the drive.

3) Even if they're skipped by defrag, these files should be shown in the list. It is kind of confusing that they don't.

4) Some sectors show as fragmented, when there doesn't appear to be anything to defragment? I can't figure this out. It seems to have worsened with the last release...

5) Piriform was developing on .NET for a while, and I can understand the benefits of moving away from that, but there were many benefits with .NET as well. Not least of which is the fact that applications are sandboxed... It would be really nice if Defraggler was run in such a way that it was sandboxed and couldn't crash Windows. I've just had such a crash, and this is not the first or fifth time...

Otherwise I love the product.

Thanks again for the phenomenal work.

I have de-installed v1.12 and have gone back to v1.10. I simply dislike the GUI of v1.11 and v1.12. The reason why I dislike the GUI is mentioned in post #236 of this thread.

I saw suggestion about options to log off and restart after defrag. Can you add ability to run some application after defrag finish?

I'm too lazy to read all topic, but i have some suggestions:

1. Ability to consolidate folder entries and place them either near MFT or in the beginning of disk

2. Ability to choose most used files and folders and move them to front of the disk

I goe d'accord - PLUS the Option: "To End of the Disk"


cheers & kind regards ^L^

How about a LEGEND displayed on the "Drive Tab" for reference of block color ID

Yes! Or even better: when you select any file by checking its box in the file list, have an option to move it to the end of the disk.

Defraggler is wonderfully useful for checking the status of drive. But when I see one file in the middle of a free area, I so wish I could move just that file, not just defrag it (it might not be fragmented).

I would like to be able to pick and delete files directly from the File List after Analyze. Usually Log files that I do not need.

Defraggler often moves a large file up and then moves it down again near the end of defrag. Moving it twice oftens wastes alot of time.

Defraggler is very slow when compacting many small files. May take an hour or more to do 1%. There should be a better way of compacting many small files that are close together.

Defraggle is generally very good, but could be better if it were more effecient.

I would like a defrag feature to sort files on disk by folder.

Lets imagine a larger disk, like 1000GB and we have installed like 30 games, each is his folder. But each folder, even with 0% fragmentation, can has all files spread along the 1000GB disk, reducing disk performance by a lot.

Example hard disk random sorted:
d:\
-FolderGame1
-SubFolder2Game10
-SubFolder1Game5
-FolderGame7
-FolderGame8
-SubFolder1Game7
-SubFolder1Game1
-SubFolder2Game2
-SubFolder2Game3
.
.
.
And that's only with folder, files can be stored even worse.


I would like to do a sort-defrag by folder, to sort files in drive stored contiguous in the same region of hard disk, reducing disk head movements and greatly improving performance.

Example hard disk sorted:
d:\
-FolderGame1
-SubFolder1Game1
-SubFolder2Game2
-FolderGame2
-SubFolder1Game2
-SubFolder2Game2
-FolderGame3
-SubFolder1Game3
-SubFolder2Game3
.
.
.

The only way I found to get something like this, is store each game on separated partitions, and believe me, it great improves hard disk performance but is a pain to manage.

I hope you will add such feature to Defraggler, thanks in advance and sorry for my bad english.

C:\System Volume Information\ should be excluded by default and should not count when calculating fragmentation. Lots of users are confused because of this.

In addition to being excluded from defrag, I would like to see System Volume Information and all the _RESTOREs moved to the slow end of the partition and left there.

---------------------

Any chance of time-stamping the messages which get written to the console?

Especially the "Defragmenting (nn%)" ones...

Thanks!

Also, when ever you start a Quick Defrag, it takes several minutes to actually begin. After it instantly analyzes, it says "Quick Defrag started." and then it takes sometimes almost as long as 10 minutes for it to actually begin or start showing the progress.

1.Minimize to system tray (also in ccleaner)
2."Check for Updates" link under help menu.
3.A button for checking the drive for errors.

By the way, keep on working hard

I suggest you obtain the statistic "Number of Free Space Fragments"
and display it in the user interface, preferably in real-time.

It is available in the built-in defragger of Vista, 2008 and Win7. (/a /v)

IMHO it is the only meaningful measure of how fragmented a disk has become
because "1%" can mean that the most frequently read thousand files of a typical
100,000 file system volume are fragmented with over a thousand fragments each!
It is much more important to prevent FUTURE fragmentation by "closing the gaps"
than to join up presently fragmented files.

Under 100 gaps is a really good result for an active system disc.

My ideal defrag program would have these options (or buttons) for each drive:-
1) Defrag files (quick)
2) Defrag space (not so quick)
3) defrag files while dfragging space (slow)
4) defrag files, then defrag space (useful when available time unknown)
5) sort files, oldest first, while defragging files and space (very slow)

If this hasn't already been mentioned: Be able to move one selected file to the end of the partition. (UltimateDefrag says they will have this in their upcoming new rev.)

I'm pretty new here, but have been using Defraggler. I really like your thoughts on portability. I'm far from 'knowledgeable' about computers, but am learning a lot. As for automatic update, it seems to me this action would have to be programmed to run preceeding a defrag when the portable device is activated.

Hi, I'm pretty new here, but lerning a lot from other members. I used Defraggler for the first time a couple of days ago. Yours is the only message here that mentions System Volume Information. Now I understand why several of my SFI file remained fragmented.

That would have been nice. Just used Defraggler for the first time, had no clue what that "graph" up there was trying to tell me. Finally dug around in "Help" enough to learn about it.
