I always wanted a file sync solution, but I used to think of it as a server for me to host, so it was always just a dream.... until I saw some creators I follow make videos about it and decided to give it a shot! It also made possible some amazing things, like having anything related to my Music directory all synced up so I don't have to use a USB cable to sync it all, all the time.

Edit: I was also considering creating an actual file sync server using Syncthing, where everything would be syncdd to the server, essentially creating an easy-to-set-up local cloud!
