Come posso estrarre / utilizzare le icone in un file icontainer?

È necessario un software specifico per aprire i file .icontainer, ad es. CandyBar .

To use an iContainer, simply double-click it in the Finder. If it is not already running, CandyBar will launch and automatically create a new collection in your icon library. You can also import iContainers by simply dragging and dropping the iContainer directly into CandyBar's List Pane. If you would like to view the contents of an iContainer before importing it into CandyBar, and you are running Mac OS X 10.5 or later, simply select the iContainer in the Finder and press the spacebar. This will activate OS X's Quicklook feature and you can browse the icons within the iContainer quickly and easily.

Hai provato LiteIcon ? Dovrebbe essere in grado di aprire i pacchetti in formato iContainer, ed è un'alternativa gratuita a CandyBar.
