It can be a struggle to figure out where all the space has gone on your hard drives. This is a handle little utility that adds a “size” tab to the properties page of Windows Explorer. Just right-click on a folder, choose Properties, click the Size tab, and you’ll see how much space is taken up by each of your folders and its subfolders and files. Use the Options button to sort by size.
This is not as pretty as the graphical output that you get from a utility like TreeSize, but it’s nice that it’s integrated with Windows Explorer.
This utility can be found at many file download sites, including here.
Let me to call your attention to my small utility Dirlot, that helps to perform just the same task as Folder Size Shell Extension does. It’s really tiny (35Kb), very visual and vivid, shortly it’s beautiful and I am its author. Just take a look here http://soft.km.ua/soft/dirlot/index.en.html
Looks good! I’ll give it a try.
As Folder Size doesn’t work on Windows 7, I tried Dirlot and it works flawlessly. Thanks Olexandr!
