Keeping old applications of pages, keynote and numbers?
I am trying to free up space on my MacBook pro. I have newer versions of pages, keynote and numbers(2017). Do I need to keep the older versions(2012) in my applications file? Can I open files made from the 2012 version if I only keep the 2012?
I was about to delete them and I got nervous that it would make those documents useless.
Thanks for the help!
