We talked about this in the office. It seems Folio is purely a viewer for a Git Repo. So yeah it is basically git so you should be able to navigate to the directory, and add a git remote.
We're tempted to use Folio and set up a remote for occasional project backups to Beanstalk.
It's only a viewer now, but if you want you can add a remote and push from the command line (or any other client)
