To run this sample

  • Press F5.

This sample contains two forms with an Explorer-like interface: a directory scanner and an Explorer-style viewer. The files that support the two forms are contained in separate folders of the project.

  • DirectoryScanner   This is a simple application that scans all directories and sub-directories in either all logical drives or a user-selected starting directory. The list of drives is obtained by using the Directory.GetLogicalDrives method. A tree view control displays the directory structure reflecting the latest scan. Directories are colored green, yellow, or red based on their total size inclusive of all sub-directories and files. The Directory.GetFiles method is used to retrieve the list of files, and the FileInfo class is used to receive the file size.

  • ExplorerStyleViewer   This is a simpler version of the Windows Explorer application. The ExplorerStyleViewer displays more file information than DirectoryScanner by using the FileSystemInfo.Attributes property. It demonstrates how to associate icons with file types by using the TreeView.ImageList property. It enables the user to run an application associated with the file type (if an association exists) by double-clicking the file (just like in Windows Explorer). Applications are started by using the Process.Start method.
