FreeFileSync is a folder comparison and synchronization tool. It supports filters, file sizes greater than 4GB, delete-before-copy for large sync operations, and creation of batch files for automated synchronization. After compare process (by date or content) operations can be customized on a file-by-file basis.

FreeFileSync Portable is in Format, automatically adjusting paths.


  • The latest version of this program is adware (offers for installation of 3rd party software), may not be open source, and locks itself to a specific path (only the drive letter may change), but a more recent version of this program (v7.9) can be made portable. Note that the update check will run whenever the runtime path changes even if you disable it.
  • FreeFileSync versions 6.3 and later can not be run from a portable menu or scheduling software due to a unfixed bug in the app.

@wagner reatto: SyncFolders has been suggested at the Forum (see where software garners more attention and testing. É só uma dica aqui do sítio... ;)

I liked this utility very much, but it stopped being portable to non-donors (being a donor in Brazil is complicated for many reasons). I looked for other similar utilities. Here I found fastcopy, I found it interesting. I had the happiness of finding SyncFolders, which is also portable. You can find it here I think could add it here.

Look at the forum topic (page 2) for more information.

Error: "Cannot open file (...)\install.dat"

Same here, and you can't just create a dummy "install.dat" - you'll get a file read error then.

So we have denigrated to personal insults now. Thanks I am Baas, appreciate your help. At least someone fixed it.

Rogerthedodger: Thanks for the notice. I've updated the entry. Please try again and post in forums if it's not working.

@rogerthementallydisabledodger - The instructions above worked when I checked them a couple weeks ago. I don't think that's changed. The version is purposely older as it's the last version that isn't broken:
