In some cases, Samba garble file names, as backward compatibility with old Microsoft Windows system that cannot handle long filenames or filenames with specific characters. It would then be shown with the form
In /etc/samba/smb.conf, in [Global], add:
mangle case = no mangled names = no
Then simply restart Samba (invoke-rc.d samba restart).
Files then will be listed with the real name. Not sure Microsoft Windows will however allow you to open the files.
