If you are using windows, Mesh from Microsoft will sync the files for you. I believe they are keeping it at 5 GB of storage.
It will allow remote access to any of your machines it's running on, and you can set up folders that stay in sync with each other. You can also drop files and get files from machines you don't have it installed on. If you add a file, it will sync to your computers.
If all you want if file sync and storage, that may work for you.
