Unless you transfer one or more of them, you have five exclusive rights to your own work:
- the right to reproduce the work (make copies) ;
- the right to adapt it (make new versions) ;
- the right to distribute or publish the work;
- the right to perform the work in public; and
- the right to display it.
Stating "all rights reserved" is simply a way of saying that you, the copyright holder, keep all those rights unless you specifically give someone else permission to copy it, display it, etc.
