Portable WinDirStat is a great tool for analyzing disk usage. It's easy to use and provides a great overview of the disk. The file categories are clearly labeled and the pie chart helps to get an idea of what is taking up space. The treemap is also helpful for visualizing the size of files and folders. I found it very useful for quickly finding large files. The search feature is handy for locating files. The only downside is that it takes a while to analyze the disk. All in all, it's a great tool.
