By default, every folder on the system receives a "Treesize" menu item in its &popmenu; (via the default &cfgfdr;). This allows you to quickly have the total tree size of every folder calculated.
After Treesize is done with its calculations, you may drag and drop new WPS folders onto the main window, whose size will be calculated then also.
Treesize offers you some settings using &popmenu;s. You may set
the sort order and the size display format. Also, you can determine whether
Treesize should also collect the size of all
extended attributes,
which takes significantly longer.
