The Ringschart is composed of a set of nested rings around a central circle. This circle symbolizes the root folder. Each ring represents a level in the directory.

Files will be painted in light gray color. Folder or file will be ignored which is smaller than 1/180 of the size of root folder.

In the case that a folder in that last fifth level contains even more subfolders, this situation will be pointed by the presence of a curve close to the edge of that folder's ring sector. When the mouse pointer hovers on one of the folders in the graphic, it will be highlighted and a tooltip will appear with information about its name and size.
