A symbolic link ( or symlink ) is like a shortcut in windows.

You can make them in the GUI ( KDE ) by draging and droping, but i'll explain how to do it on the command line.

The command is 'ln' - link. And the option is '-s' for symbolic. So ..

ln -s /home/some/fileordirectory /home/the/target
( from ) (to)

Hope this helps.
