I just set up Rasbian with samba and it's working fine. I can copy everything from my windows computer to the samba share on de raspberry.
It goes wrong when i try to copy files with some chars like ó é ê in the filename. Windows then give me the message that the file is to large (not true).
I did try some charset modifications in the smb.conf file with no luck. I am certainly missing something. Not very experienced with this.
