If you have hard link inside some directory and then you make some changes on file created with hard link than that file won't be affected because they don't share common address space so there is no sync between that two file. If you create file with symbolic link and the edit file cretaed with symbolic link original file on which that link points will be changed. If you delete symbolic link original file won't be deleted but if you delete original file than a symbolic link is also deleted because they share common virtual address space and sync is possible between that two files.

You don't need to use (multiple) hard links or soft links. They are sometimes a very useful facility but you can live without them.

when they will be use full
