Unison is a synchronization tool that allows two collections of files and directories to be stored on different hosts or different disks on the same host. Unlike simple mirroring or backup utilities, the program can deal with updates to both replicas of a distributed directory structure. Updates that do not conflict are copied automatically while conflicting updates are detected and shown.

The program is cross-platform (OS X and Linux). X-Unison is a wrapper program for Unison.

Runs on:Win95 / Win98 / WinME / WinNT / Win2K / WinXP
Writes settings to: Application folder
Unicode support: Yes
License: GPL
How to extract: Download the ZIP package and extract to a folder of your choice. Launch PortableUnison.exe.

Note: a blank console window is always visible when you run Unison. This is explained on the author website.

Much needed portable (both as in platform independent as in system independent) utility for advanced users. Softpedia download links is dead, but BigD has a working solution (after proper launcher batch script customization) at the link in the previous post. :)

You may be interested to know that I've made a portable package of a relatively recent version of Unison (2.40.16) available here: http://appstogo.mcfadzean.org.uk/index.html#file

Hope this helps some of you.

Hi. I've always run the regular Unison from batch files without needing this Portable version, but apparently installing the latest DOT NET and resulting MS updates to my Win7 causes the GTK DLLs to no longer load from the path (I was pointing to the bin under Portable GIMP).

One fix is to install the GTK runtimes directly to system32.

This PortableUnison launcher is another. It seems to works fine with an updated unison binary, as long as you also update the GTK bin folder with a newer runtime.

Note also that (perhaps as a result of the same updates), the unison executable is triggering UAC to launch within the administrator environment, which then causes drive letter mappings and the environment variables set by my batch files to no longer be recognized:


So I've created a batch file to set these (along with NET USE to re-map the drive letter to the share) and then launch the PortableUnison.exe. This batch then needs to be launched "as admin" to keep everything consistent.

Hope this helps others, and sure wish a clean updated version of this could be created by someone more knowledgeable than me. 8-)

Plus, PortableUnison seems to run fine without gspawn-win32. (At least so far, so good :)

The alert concerns a file in gspawn-win32-helper.exe not in the core of Unison. It is fair to think that the "library" is used enough to be exempt from false positives.

It is up to the user to determine the level of risk he is willing to take. If you want to have a drink in a bar and it looks like there are dangerous people in a specific bar based on your heuristics, would you enter it? That is the same thing - you have an "educated guess" that there is a trojan in that "library" which is not impossible.

IMHO if you are do think that this is a false positive, it is possible to submit it to the respective antivirus vendor. That is in my opinion the only 'right' thing to do - I did the submission of the file.

In the mean time, I can only repeat what I said: carefull!

@Mario, it's detected as Trojan.ADH, this is a heuristic detection from Symantec, this means it LOOKS like a trojan, not unusual for a backup app like Unison.

I can get a later version of Unison to run OK, despite it throws up a couple of error messages. It would be nice to find a way to be able to update Unison without the errors.
