From the Desk of Mr Daniel

A few students who are using Mac approached me during ISPL Week and PW Lesson inquired on how to zip (Compress) and unzip (uncompress) files using Mac. Mac OS X has the ability to create ZIP compressed files from within the OS :

To zip, Control-click on the file and choose Create Archive. Or you can click on a file, then go to the Action menu (the button that looks like a gear up in the Finder window’s toolbar), and choose Create Archive from there.

You can also compress several different files (like three, for example) into one single archive file — just Command-click (or Shift-click contiguous files) on all the files you want included, then choose Create Archive of X Items from the Action menu. A file will be created named “Archive.zip”

If you need to open a ZIP file, don’t sweat it — just double-click it and Mac will automatically decompress it.
