Installing FreeFileSync in Ubuntu

 January 13, 2021      Stardate: 74501.0     Tagged as: Ubuntu FreeFileSync

(2021-02-09): As of v11.6 FreeFileSync uses an installer. I don’t believer these instructions are valid anymore. The package you download is now a .zip containing a .run and a .key file. From terminal you execure the .run file, or you could probably double-click it. It asked to accept the license terms and then asked to accept the installation location. It was pretty slick!

Go to and download the latest version for Ubuntu. For most browsers, the default download location is the directory ~/Downloads.

Where do you install your personal software? This is something you may or may not have an opinion about, either way you need to make a decision. When you install software through Software Updater or apt-get the location is /bin/<package> but it’s generally accepted that you don’t put manually-installed packages there.

The Linux Standard Base and the Filesystem Hierarchy Standard are arguably the standards of where and how you should install software on a Linux system and would suggest placing software that isn’t included in your distribution either in /opt or /usr/local/ or rather subdirectories therein (/opt/ /opt/ /usr/local/bin).

For me, I “install” in /opt/ so these instructions assume that location.

sudo tar -zxvf ~/Downloads/FreeFileSync_*_Linux.tar.gz -C /opt

This command extracts the compressed tar and puts the contents in the /opt/ directory. The contents are already contained within a directory named FreeFileSync, so need to create one.

Next we need to create a shortcut. There is an example shortcut file provided as /opt/FreeFileSync/FreeFileSync.Example.desktop that you can copy and then edit, but I find it easier just to create a blank file and copy/paste text. Type this command to create a file and open it in an editor.

gedit ~/.local/share/applications/FreeFileSync.desktop

Copy the text below into the empty file, save, and close.

[Desktop Entry]
Comment=Keep files and folders synchronized
Exec=/opt/FreeFileSync/FreeFileSync %F 

You can do the same for RealTimeSync if you want.

gedit ~/.local/share/applications/RealTimeSync.desktop

Copy the text below, save, and close.

[Desktop Entry]
Exec=/opt/FreeFileSync/RealTimeSync %f

Updating FreeFileSync

When you want to update versions, simply “install” the latest version into your installation directory per the instructions above. For example, let’s say you have version 11.1 and want to update to the latest version which happens to be 11.5. In this example, I assume you have previously put the package in \opt\FreeFileSync\.

Download the tar.gz file, uncompress it into the existing \opt\FreeFileSync\ directory. Done.
