The Flex file system components combine the functionality of other Flex controls, such as Tree, DataGrid, ComboBox, and so forth, with pre-built awareness of the file system on the application user's computer. These controls duplicate the functionality of user interface controls that are commonly used in desktop applications for browsing and selecting files and directories. You can use one or two of them to directly include file-related functionality in a screen of your application. Or you can combine several of them together to create a full-featured file browsing or selection dialog box.

Each of the Flex file system controls except the FileSystemHistoryButton control displays a view of the contents of a particular directory in the computer's file system. For instance, the FileSystemTree displays the directory's contents in a hierarchical tree (using the Flex Tree control) and the FileSystemComboBox displays the directory and its parent directories in the menu of a ComboBox control.

For any of the Flex file system controls except the FileSystemHistoryButton control, you use the control's directory property to change the currently selected directory for a control. You can also use the directory property to retrieve the current directory, such as if the user selects a directory in the control.
