how can I access windows shared folder?

http://www.ubun2.com/question/226/how_mount_and_access_windows_shared_folder_ubuntu_linux

You need smbclient to access windows folder for linux
Open a terminal and issue the following command
 
sudo apt-get install smbfs
 
this will install the smbclient as well as the smb file system. smb file system is useful if you want to mount the windows folder in the ubuntu file system.
 
In case if you just want to access the windows folder, just install the smbclient itself without the smbfs
 
sudo apt-get install smbclient
 
Now open the File Browser in ubuntu, using Places->Computer menu link
in the Location bar just type smb://<windows m/c ip or name>/<shared folder name>
for eg. smb://192.168.1.10/Public
