FolderSizes installs a powerful extension to the Windows shell context menu. This extension allows you to right-click any normal folder within Windows and run key FolderSizes reporting functions against it.
If FolderSizes is already running when one of its shell context menu extension items is selected, it will perform the associated task immediately. If FolderSizes is not already running, it will be launched automatically, and will proceed to scan the specified path.
The context menu extension provides access to all FolderSizes File Reports, as well as the normal scans (the results for which are shown in the main user interface).
Note: The shell context menu extension folder can even be accessed from within FolderSizes itself. Simply right-click a folder within the Folder Browser pane, and you'll see that the shell context menu is still available (and works as expected).
