Installation

The latest release can be downloaded from GitHub.

Standalone on Windows

Standalone builds support Windows 8.1 or later. Windows 7 may work (until it doesn't). WinFsp must be installed.

ninfs-2.0a9-win32-installer.exe contains WinFsp and will automatically install it if needed (though it will not update it).

ninfs-2.0a9-win32.zip requires WinFsp to be installed separately.

Standalone on macOS

ninfs-2.0a9-macos.dmg contains a signed and notarized application for Macs with Apple Silicon and Intel. Requires OS X 10.9 and later. macFUSE must be installed separately.

As a Python module

ninfs is available on PyPI and can be installed like any other package. Python 3.6.1 or later is required. Support depends on the availability of libfuse 2.x or a similar implementation. Nintendo Switch NAND support requires OpenSSL 1.1 or later (pre-included for Windows and macOS).

• Windows: py -3 -m pip install ninfs==2.0a9
• Linux and macOS: python3 -m pip install --user ninfs==2.0a9

Usage

Graphical interface

The GUI can be started in various ways depending on how it was installed.

• Windows: Find "ninfs" in the Start Menu. Or run ninfsw.exe in the standalone release.
• macOS: Run the ninfs application. If this is the first time, Gatekeeper might ask you if you are sure you want to start it.
• Python module: Run the ninfs module with the gui argument. Example:
  • Windows: py -3 -m ninfs gui
  • Linux and macOS: python3 -m ninfs gui

Command line

Mount types can be accessed through the command line in all setups.

• Windows: If added to PATH, use ninfs <type>. For example: ninfs cia game.cia E:
• macOS: Use the ninfs binary in the application. For example: /Applications/ninfs.app/Contents/MacOS/ninfs cia game.cia ~/Desktop/cia
• Python module: Use the ninfs module. For example:
  • Windows: py -3 -m ninfs cia game.cia E:
  • Linux and macOS: python3 -m ninfs cia game.cia ~/Desktop/cia
• Python module entrypoints: If Python is added to PATH (by default it is not on Windows), entrypoints can be used. For example: mount_cia game.cia ~/Desktop/cia
