Folder Size Shell Extension is a very simple application that adds a new tab to the “Properties” screen of any folder, allowing you to view its size on the go.
In essence a shell extension, this little utility comes with no dedicated interface beside the information you can access via the “Properties” menu, which is actually a list of the folder contents along with the adjacent size.
Simply install the application and you should be ready to go. In some cases, a computer reboot is necessary, so if you can't see the “Size” tab a restart may fix the problem.
Besides showing folders sizes, Folder Size Shell Extension also comes with a few options, including “Units”, “Reorganize” and “Display”, allowing you to customize the tool just a tad.
There's no help file whatsoever, so those of you who may have problems working with the app have no other option than to try search for an answer on the web.
