Folder and File sharing between Linux and Windows

My fists choice to share files between my Linux and Windows machines was file transfer through messengers .. isn't funny?

Yea.. it is funny, but this due to my laziness to Google it

But now every thing is okay and I can freely share files between my 2 PCs

So to summarize:

To share files between Linux(Ubuntu) and Windows(Vista) you can use Samba

Samba is a free software re-implementation of SMB/CIFS networking protocol. Samba is released under the GNU General Public License. Samba provides file and print services for various Microsoft Windows clients and can integrate with a Windows Server domain, either as a Primary Domain Controller (PDC) or as a Domain Member. It can also be part of an Active Directory domain. Samba runs on most Unix and Unix-like systems, such as Linux, Solaris, and the BSD variants, including Apple's Mac OS X Server (which was added to the Mac OS X client in version 10.2). Samba is standard on nearly all distributions of Linux and is commonly included as a basic system service on other Unix-based operating systems as well.
