Node also works hard to ensure other functionality built on the technology is operating-system-agnostic. Sometimes it succeeds, and sometimes we need a little help from third-party modules.
This chapter provides a more formal introduction to the File System. In addition, it looks more closely at OS-specific functionality and differences.
