This is a basic function on the Mac operating system. Why is it so hard on a Windows machine? I don't want to have to click on a folder and open it to see and have access to the files inside. On the Mac finder, there is a caret to the left of a folder and you just click on the caret and the folder expands to show the contents of the folder. I've looked all over the place for a way to do this on Windows and can't seem to find how to do it. Tree view? Hidden files and folders? Nothing works.
