This is a brilliant piece of software. It is simple to set up and easy to use. I have been using it for a few months now and it has never crashed. I use it to sync to my Dropbox via BoxCryptor encryption. I don't completely trust auto syncing software, so this is a great alternative. It allows you to keep your original files on your computer, and also save separate back up files on your external drive or Dropbox etc. Well done guys!

Flexible. Does what it's supposed to do well. I switched from SyncBack (free version) to FreeFileSync because it handles a few important things better, e.g. copying locked files, more powerful filters.

Most useful application. During all these years that I've been using it, it has gotten better and better.

The most amazing and useful piece of software I have. Particularly the versioning feature, which allows me to perform my backups with file history in a more useful manner than general backup software. It works well and is well designed.
