With the development of network technology, our demand for file synchronization and backup is also becoming stronger. While various web disk services provide us with convenience, they also bring a lot of restrictions and risks in terms of speed, security and privacy. There are many cloud synchronization solutions, such as Seafile and Nextcloud, which are feature-rich but bulky and difficult to deploy cloud disk programs. But if we only need to synchronize files, then a better choice is Syncthing. In comparison, it is lighter, easier to deploy and use, more secure, and especially has faster file transfer.

Syncovery (formerly called Super Flexible File Synchronizer) is currently the most powerful and flexible real-time, automatic synchronization & backup tool, developed by Super Flexible Software from Germany. Since Version 6, it has changed to use now easier to remember and understand new name Syncovery, but its functions are exactly the same as Super Flexible File Synchronizer.
