Subfolder Depth

By default, FolderSizes shows subfolders in the graph and detail view at a single level of depth. That is to say, only immediate children of the scanned drive or folder are displayed, and you can then "drill into" any subfolder by double-clicking them (either in the graph or in the detail view).

Setting the subfolder display depth to more than a single level will produce detail and graph views that contain subfolders matching that depth. Setting the subfolder display depth to 0 (zero) will cause the detail and graph views to display all levels of depth (which, on large drives or folders, can produce very large report data sets indeed).

Note: The current subfolder display depth can also be switched instantly via the View menu.
