FolderSize - integrate overall folder size into Windows Explorer

This feature is something that would be have native in Windows instead of applications that rarely get used or get in the way. It runs as a service in the background to take inventory of folder sizes, which I find more useful than indexing files and their content like how the new Vista index engine works and/or Google Desktop. Maybe I am a bit of a directory/file structure "Nazi" with the way I arrange my files but typically needing to use Search to find files on your hard drive means you are not storing them in a coherent manner. Of course, I say that, and by contrast my desk is quite messy usually from the amount of chaos going on around it.

Anyway, this program has lessened my need to use TreeSize, which is also an excellent program.

The 'Feedback' section of that website is rather amusing too.
