The Explorer file manager is used to view files as well as create, copy, move and delete files and folders. Also called "Windows Explorer" and "File Explorer," it displays the folder hierarchy in the left windowpane of all the internal drives and any connected external drives. To learn more about how files are organized, see Win Folder organization. When you click on a folder in the left Explorer window, its content appears in the right window. You can launch two or more instances of Explorer and drag and drop between them, although you can use Cut, Copy and Paste with only one instance of Explorer (see Win Copy/move files/folders). Following are the basic Explorer operations: LAUNCH EXPLORER Right click the Start menu, and select File Explorer, Open Windows Explorer or Explore, depending on Windows version. DISPLAY CONTENTS OF A FOLDER Click the folder in the left windowpane, and its contents are displayed in the right windowpane. OPEN FOLDER IN A NEW WINDOW To open a folder into a new window, right click the folder in the left windowpane and select Open in New Window (Win7, 8.1 and 10) or Open (XP). DISPLAY NAMES OF SUBFOLDERS ("Expand the Tree") A greater-than sign (Win10) or right-facing triangle (Win7 and 8.1) or a + sign in XP to the left of the folder means that the folder contains subfolders (other folders inside). Click the triangle or + sign to reveal the subfolders beneath, and the triangle becomes dark and points downward, or the + sign changes to a - sign. DISPLAY CONTENTS OF A SUBFOLDER Click once on the subfolder icon in the left window, or double click on the subfolder icon in the right side.
