DiskFerret analyzes the files in any hard drive, network share, or folder, producing charts and info to show you exactly where and how your disk space is being used! With DiskFerret, you'll be able to quickly identify the largest folders and files, oldest files, and duplicate files, as well as the most egregious disk-munching users on your network. And it's not just for show, either — DiskFerret gives you everything that you need to delete these files, or ZIP them up for archiving!
This is a must - I have installed it and already found files to remove and freed up more space….
