If you want to connect to shared drives or folders on Windows based computers, this can be accomplished by simply opening up the Konqueror web browser/file manager.

To do this:
Make a note of the computer name of the system that holds the share you want to access. Also make a note of the primary user name (or administrator) that you use to log into that computer.

Open up Konqueror (you should know where it is by now). In the address bar, type

'smb://(username)@(computername)/'

This should bring up a window prompting you for a password. Enter the password for that username to see the shared files. You may have to refresh the window once or twice before the password prompt comes up.

If you want to share files from your SUSE Linux computer, right click on the folder you want to share and choose 'properties' then 'local net sharing' and 'configure file sharing'.

This window gives you the option of sharing files from your home folder.

Now you can right click the same folder again and the 'sharing' option will be available in the menu. This functions similarly to Windows, as you can see from the screenshot below.
