For those who work on multiple devices and operating systems or who want to securely access photos and music between devices, Syncthing may appeal. Sycnthing is an open-sourced, encrypted syncing tool that users can download for a variety of operating systems (including Linux, Windows, MacOS, and Solaris to name just a few) or install as an application. To access files on another device or systems, users can simply download their folder of shared items. All shared items are also backed up securely. One unique feature of Syncthing is that it includes File Versioning options, which allow users to save and archive older versions as they continue to work and update a file.
