The "Treesize" program displays the disk usage of a folder and all its subfolders in a tree view. If Treesize is started with a directory name as a parameter, that directory is displayed, or the current directory otherwise.

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.
