TDirectoryTreeView is a TreeView control that is aware of the drives and directory structure like Windows explorer. TFileListView is a specialized list view that lists all the files in a specified directory and the list automatically refreshes on any changes in this directory. All view styles (Report, Icon, SmallIcon, List) are supported. The items are sorted in A->Z or Z->A order if the user clicks on any header. Component automatically determines how the items should be sorted, as letters or as numbers. Items will be sorted correctly (unlike Windows Explorer), even if filenames contain mixture of letters and numbers. Whenever a file is created or deleted in current directory, the TFileListView automatically refreshes.
