Try this excellent solution:
jar xvf COCR2_100.zip
- drag and drop file into terminal window.
- use keyboard arrows to navigate to start of line in terminal
jar xvf in front of your file name, remembering to leave space before the start of your file name.
- grab a beer and watch terminal work its magic as it extracts files.
The location of where the new files go varies, but usually best trick to find them is click on your computer name in Finder which should display most recent activity at top of all files.
jar command is not available, you can install
fastjar by pasting the following in terminal:
sudo apt-get install fastjar
