What an amazing pet! I've been agonizing over installing nfs and all its dependencies, and this 4mb program does it all in a single directory and no other pet other than java (which is available as an SFS) is needed.
For the record, a Nokia 9300 can be browsed (MMC card, too) with this app. In "connection line," I abandoned channel choice and simply typed in the phone's address and nothing more. Voila. The phone's C and D drives appear.
