Here is a guide to share files and folders in a windows network.
First you need to install the system-config-samba package. Open a terminal (press SuperKey and type terminal) and copy+paste the following line:
sudo apt-get install system-config-samba
When the package is installed close the terminal window and press Alt+F2 and type: samba. Click on Preferences and select the server settings. In the Workgroup text field you need to enter the name of your windows network. When done you can close the samba server configuration window.
To share a folder click with your right mouse button on the folder that you want to share and choose Sharing Options. Click on the checkbox in front of Share this folder and enable allow others to create and delete files and guest access if you want. If you don’t enable guest acces then you will need to make a new user account on Ubuntu and use that account to get acces to the shared folder from a windows machine. Now clcik on the Create Share button and on the Add the permissions automatically button.
If you are asked for a username and a password when trying to open your shared folder you must add your Ubuntu account to the Samba user database. To do that copy+paste the following line in a terminal window:
sudo smbpasswd USERNAME -a
First you will be asked for your password and after that you need to enter a new samba password.
If you can’t detect the shared folder on windows 7 make sure that file and printer sharing is enabled.
To enable file and printer sharing on windows 7 start Windows and in the search box type:
manage advanced sharing settings
Under Public folder sharing enable the Turn on sharing option and restart Windows.
