DSynchronize lets you copy, move, or synchronize folders on your computer or over a network. The program can sync in both directions, making both folders up-to-date with the latest data, do realtime sync where any changes copied to destination and even verify it's transfers. The program can schedule operations, add timestamps to the destination folder and keep multiple backups (iterations).

If in use, the program can even eject a USB device when an operation is complete.

The executable depends on MSVBVM60.DLL - MS Visual Basic VM, so isn't truly portable.

Cosmin 2006-06-01 23:27

actually all you have to do is place the dll in the same folder as the application. So I'd say it is portable.

Kataphract 2006-06-09 21:04

The MSVBVM60.DLL is bundled in Windows 2000/XP/2003, so isn't necessary to place the dll in the same folder.

Although not the most user-friendly sync program available, I've tested it for two months now and found it to be excellent for portable syncronization.

The only thing I don't like is it cannot work on unicode file name.

linuxamp 2007-08-31 02:11

Joe, it displays UTF filenames as gibberish in the source and destination panels but if you try to synchronize you'll see that it both UTF folder and filenames sync properly.

linuxamp 2007-08-31 02:17

Certainly doesn't win any beauty contests but functionally perfect... almost.

1) Interface is intuitive
2) Includes just about every option one could want in a synchronizer
3) Good command line support for task scheduling or scripting

I only have one tiny gripe with this program. If your source directory is C:\folderA and your destination is D:\backup, it will put folderA contents in D:\backup not D:\backup\folderA.

I'd agree with Webfork ... not the most user friendly but does the job. The ability to specify individual files as well as folder level sync is the differentiator. I use this forend of day back-up to a portable HDD ... it's a great little tool, is portable, and it's free!

jcatech 2007-09-27 20:32

Great utility but the filter does not work in service mode.

Webfork 2007-11-20 15:56

Addendum to my previous note: been using the program regularly and often for about 6 months now on multiple computers and multiple configurations. To this point, there is NO OTHER sync program for my purposes.

Some requests: An "rsync" style sync method that only transfers *changed* data; resending an entire 1 gig file when only a few bits have changed is time-consuming and wasteful. Also FTP capabilities would be nice.

Turpin 2008-01-30 20:53

It doesn't allow you, by default, to have different synchronization settings (2-way or 1-way, etc.) for each sync pair, BUT you can run multiple copies of Dsynchronizer from seperate folders, each doing seperate jobs simultaneously, which totally solves that problem for me. I just create a group of shortcuts, one for each synchronization job, each leading to the dsynchronizer.exe in the specific dsynchronizer folder. If you plan on running more than one, I don't recommend running it as a system service. I had some sort of problem with that.

Hephaestus 2008-08-28 16:16

Good but not great. It lacks is good file and folder attribute support, it does not, for instance, copy the attributes that let folders have special icons defined in a "desktop.ini"...

NeedAnswer!! 2009-01-27 06:13

okay there is always but. :D
I found this program useful in every case i faced but it doesn't function when you run it as a service.
set and enable timer works in normal mode but doesn't in service mode
also the real time synchronization option doesn't work for me :(

can you tell me your opinion about that.???

Webfork 2009-02-17 15:54

To NeedAnswer's real time issue:

Make sure you run a system sync all the way through before enabling "real time" sync. Otherwise, I don't know what the issue is. In the limited tests I've done with this feature, its worked fine. I recommend contacting the author (click the "Website" link at the top of the page).

Hugh H. 2009-04-07 14:48

When you "sychronize" with this software, the FIRST thing it does is DELETE every file in the destination path that isn't in the source path!!!
And it does it in a flash! It does not default to leaving your files alone! It defaults to kill.

This has to rate as the stupidest "default" behavior in the universe.

Chris L. Franklin 2009-04-24 11:30

@Hugh H. : Why did not run it in test mode first.. did you not see the test mode check box, did you not see the DO NOT DELETE checkbox.. are you sure it's not just your "stupidest "default" behavior" (aka being a click happy end user) that caused/is the issue ?

I'd have to say I love this program, although I do wish it would support shadow copying and per source+dest scheduling (I don't need or want everything to have to be real time, when I really only want 1 thing to be real time).
But other then that, it runs GREAT.

Jens 2009-09-25 13:38

Well, there may be issues with this program but it is BY FAR the very best synchronization and/or backup program I've used. There's only one tiny thing I dislike about it: When looking in the log file it does say "OK" under the summary in the beginning even if a file has been marked "FAIL" and not been copied.

Erase+undelete 2010-01-18 18:43

Be sure to enable "do not delete any file" during testing :)
It saves you a lot of work, it should be a default entry....

Turpin 2010-01-25 09:19

Dsynchronize is one of the most complete and straightforward solutions for file synchronization for windows that I've found. Do pay attention to the "do not delete files" option and make sure it's checked if you need it. And I recommend testing synchronization between two newly created folders with no important files contained within before risking your important data. It's standard procedure for me, because you should never take for granted you know what any software will do.

Wazza 2011-03-26 06:21

Some questions --- How can I set Dsynchronize to always open in "Preview mode"
How do I use the Backup changes feature.


Victor 2011-04-06 06:06

I think as long as you check the box "save on exit", it would be ok, it would save all ur current setting when exit. as for backup changes, I also want to know that, cos I am doing a documentation for my team...


Wazza 2011-04-07 01:20

Unfortunately "save on exit" only helps if you remember to check "Preview mode" before you exit. I want to ensure I always Preview and look over proposed changes.
(As I understand it, preview makes no changes.)

Then I uncheck Preview and do the actual sync . and give or deny permissions as it progresses.
If you exit then, and forget to check Preview it will not be selected next time.


Victor 2011-04-08 02:47

@Wazza: Ok... I see, you check, and see the changes, then uncheck to run the actual sync, and then, you really have to check again to be saved before exit, it is case by case...


TP109 2012-10-26 12:02

Extremely fast synchronization. Because of this, you need to be careful with this one. Preview should always be checked and the results reviewed before a real run to make sure it behaves as intended. Not using preview may mean lost data in nearly the blink-of-an-eye. Otherwise, this is a great utility, especially useful for synching non-critical data.


lwc 2013-05-22 12:28

It doesn't save settings for me. Thus I can't use multiple profiles.


lwc 2013-05-24 20:39

Correction, it only happens when I run it under Sandboxie.


ahmedemad 2015-03-28 13:42

I used Dsynchroinze and It was great and all... but I had to sync a drive but it deleted everything in the desination.. does anyone happen to know any way to recover the deleted files?


Midas 2015-03-30 10:21

@ahmedemad: you might try Recuva, for example (http://www.portablefreeware.com/?id=1139)...


smaragdus 2015-05-21 02:18

Latest version of DSynchronize (2.30.9) fails to run on my system (Windows 8.1 x64)- it opens and exits almost immediately. This never happened with any version prior to 2.30.9. I contacted the developer but haven't got any response so far. If he had responded I would have provided him with the dump files.


webfork 2015-05-23 01:58

Thanks for trying. Dsyncronize has been a reliable program and the developer has been fairly active over the years. I hope he gets back to you.


Hugh0202 2018-05-02 14:37

Maybe I misunderstood "synchronize"? If I have a and a , I want the destination folder/tree to mirror the source. This doesn't do that.
I thought I'd use this to maintain a second copy of my digital music collection, but when I did a bunch of tagging and renaming, and use this, the destination files were not renamed. I don't expect a utility to detect if the content has changed -- I just wanted (and want going forward) my "backup" to be exactly like the original -- with extra files and folders gone, and new ones copied. This requires a "utility" because much of the change to the source involves cleaning up filenames, so drag-n-drop produces two (or more) "copies" of the same songs in the backup.
