Saturday I needed to go to a party of a friend which graduated. I connected fine (as usual ) to www.labisana.it and downloaded the map ("Come raggiungerci"), but... couldn't uncompress it!

How is it supposed to uncompress zip files? It has been quite a lot since I do not work with Linux on my desktop, so maybe there is a simple tar command or so on, but I could not get it..

Thanks for your replies
