Via My AppFree, BlueFTP isn't quite what you think it is. It's nothing to do with FTP, the File Transfer Protocol across the Internet, rather it's to do with the same named protocol over Bluetooth, i.e. between local devices that are paired over Bluetooth. And, as you might expect, this also handled contact records, possibly the best known Bluetooth data exchange.

From the Store listing:

Browse, explore and manage files of any Bluetooth ready device, using File Transfer Profile (FTP), Object Push Profile (OPP) and Phone Book Access Profile (PBAP). Support of double screen file management and drag&drop between managers.

BlueFTP is also a powerful file manager.

Some of the promo screens of BlueFTP in action:

Clean and clear file/object management - with landscape mode doing a better two-pane job (pro tip!)

Copying a couple of photo files from a connected phone; (right) browsing possible connections/devices.
