MicroSD Management

This is the New_3DS-only system application used for microSD data transfer for New3DS<>PC. This is launched via System Settings.

Going by strings in the application, it appears this uses SMB. When first starting the application it will ask for an username, password, and workgroup name, for accessing the New3DS with from a PC. These settings are then stored in savedata, so that info doesn't need setup each time the application is launched.
