// facade c.Files(): folder create, upload, stat, list, rename, move, copy,
// delete. Writes must go to REST (the default writeOrder), reads follow
// readOrder (REST when no SQL backend is registered) and every returned Entry
// must report its provider. Destructive — throwaway project, cleaned up.
