Pyfilesystem is a Python module that provides a simplified common interface to many types of filesystem. Filesystems exposed via Pyfilesystem can also be served over the network, or 'mounted' on the native filesystem.

Pyfilesystem simplifies working directories and paths, even if you only intend to work with local files. Differences in path formats between platforms are abstracted away, and you can write code that sand-boxes any changes to a given directory.

Pyfilesystem works with Linux, Windows and Mac.
