We probably spend the most time on our Macs interacting with various files in the Finder and on the Desktop. If you have been using a Mac for a while, you know several ways to Preview files before using them. I thought I knew just about every way possible to Preview files on the Mac until I saw this very thorough video. I learned a couple of new ways to Preview files and was reminded of other ways that I had not used in a while. This video is a good reminder of how you can Preview files on your Mac.
