What is using all the space on my hard drive? I’m sure you have asked yourself that question, and it can be hard sometimes to know where to look for the big files that you might be able to delete to free up space. Well, there are apps for that of course. My favourite is called GrandPerspective, and can be had at http://grandperspectiv.sourceforge.net.
Its key feature is that it gives you a graphical overview of your files while preserving the nested folder view as well. From this view, you can easily see and even delete any and all files you do not need anymore. Try it, I bet you can free up a ton of space!
