FTP (File Transfer Protocol) is a way to transfer files wirelessly through a network. While New3DS models are capable of performing a similar function with microSD Management, there are a number of downsides:
- microSD Management does not exist on Old3DS models.
- microSD Management is only compatible with Windows.
- microSD Management uses an outdated protocol (SMB v1.0) that constitutes a security risk. It is therefore disabled by default on modern installations on Windows.
Luckily, with custom firmware, we can instead use FTP to transfer files wirelessly on both New3DS and Old3DS.
