If you are a Windows user who never bothered to change your file display to ‘details’ and just use large icons in Windows Explorer, this will be of little interest.
Folder Size Explorer Extension adds a new column to the Details view in Windows Explorer. The new column shows not only the size of files, but also the size of folders. It keeps track of which folders you view, and scans them in the background so you can see complete size of all files within the folder. It’s very useful for cleaning up your disk. Once you get used to having that information available, a directory listing simply looks incomplete without it!
And it works like a charm. For W2K and XP.
