I used to use sync.com (still do until my contract runs out). I switched to #filen #filen_io because I'm moving from Windows 10 to #linux_mint ). After some initial pain on windows (synced files were going the wrong direction), and some helpful advice from Filen's support team, I now have an account on 4 computers: Windows, windows, mac, and Linux, not to mention several mobile devices and tablets. I am happy to say it's all going great, and I love that I am supporting a smaller team.
