Very simple file sharing between FreeBSD server and windows client ?

[Frank Bonnet]

Hello

Is there a simple software to share files between a FreeBSD server and a 
windows client other than Samba which is a bit overkill for my needings,

I just want to share a directory (and subdirectories) of my server with 
ONE Windows client, to facilitate some files exchanges between two users.

Thanks for any infos
