For sharing files with Windows you just have to follow this steps:

Got to System > Administration > Shared Folders

  • in the Shared Folders tab add the folders you wish to share
  • in the General Properties tab type the Workgroup of your Network (as in Windows)

In the Terminal add yourself as a Samba user:

sudo smbpasswd -a yourusername

That’s it. You can now access your shared folder using you Linux user.
