Wii U:FTP

FTP (File Transfer Protocol) is a way to transfer files wirelessly through a network.

Luckily, with custom firmware, we can use this method to transfer files wirelessly to a Wii U instead of moving the SD card back and forth each time.

What You Need

On your computer:

A working FTP client
- Windows: Use WinSCP
- macOS: Use Cyberduck
- Linux: Nautilus or Dolphin, the file explorers for GNOME and KDE respectively - if not usable, use gFTP instead

On your Wii U:

The latest release of ftpiiu (FTPiiU)
- Download the ftpiiu.zip file, extract it and place the wiiu folder in the root of the SD card

Insert your SD card into your computer
Extract the contents of ftpiiu.zip and copy the wiiu folder to the root of your SD card. Merge if asked.
Insert your SD card into your Wii U
Ensure your Wii U is connected to the same Internet connection as your computer
Open the Homebrew Launcher (Mii Maker for Tiramisu)
Navigate to FTPiiU
Touch it and press Load

If you haven't already, install the FTP client for your operating system
Open the FTP client and fill in the information as follows:
- File protocol: FTP (not SFTP)
- Host name/IP address: The IP address displayed on the GamePad or TV (e.g. 192.168.0.67)
  - This is a local IP address, so you don't need to censor it if you need assistance
- Port number: Usually 21 by default, so leave it blank
  - If you don't see this option, instead type (ip):(port) into the host name/IP address box, e.g. 192.168.0.67:21
- Username/password: If you see a checkbox for "Anonymous login", then enable it; otherwise, just leave it blank
Click "Login" or "Connect"
- If prompted to enter a username or password, press ENTER to leave it blank

Your computer is now connected to your Wii U via FTP!
