ICO file extension is a container file format that may include several icon images of different sizes. I'd like to know how I may access and view what is inside a ICO file, i.e. the different images it contains, and possibly any metadata.

          The built-in Preview.app can handle ICO files and show the contents of the container. It can also show the file metadata. To view file metadata, use the keyboard shortcut, Command + i.



          enter image description here



          Right click on one of the images, select Export As... and select the desired format.

          • Nice! Thank you, Nimesh. I would have a subsidiary question: why, when I right-click on the ICO icon in the Finder, don't I see 'Show Contents'?

          One-line joke

          A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
