You specify the directory whose content is displayed by setting the directory property to an instance of the flash.filesystem.File class. (File instances can represent directories as well as files.) Whenever this property changes for any reason, the control dispatches a directoryChange event.

You can set the enumerationMode property to specify whether to show this directory's files, its subdirectories, or both. There are three ways to show both files and subdirectories within each tree node: directories first, files first, or intermixed.

You can set the extensions property to filter the list so that only files with the specified extensions are displayed. (Extensions on directories are ignored.) You can also specify an additional filtering function of your own by setting the filterFunction property.

You can use the showExtensions property to show or hide file extensions, and the showIcons property to show or hide icons.

You can do custom-sorting within each tree node by setting the nameCompareFunction property to a function that compares two file or directory names.

If the user double-clicks a closed directory node, or clicks its disclosure icon, this control dispatches a directoryOpening event. If the user double-clicks an open directory node, or clicks its disclosure icon, this control dispatches a directoryClosing event. A handler can cancel either event by calling event.preventDefault() in which case the node doesn't open.

If the user double-clicks a file node, this control dispatches a select event.
