Internet Explorer and Firefox can do more than just surf the web! Use them to open all sorts of files.
Just drag and drop a file into your browser window and watch it open. It comes in handy, especially for looking at JPEG’s and GIF’s, but other files work, as well. It can also open text files, and provided you have the correct Office software installed on your computer, it can open some of those, too! Experiment a bit and see what you come up with! Just drag a file over into an open browser window!
