When an object contains more objects at a lower level in the hierarchy, like drives or folders, it is preceded with a plus or a minus sign. To view the next level down in the hierarchy, click on the plus sign to expand the branch. To collapse a branch, click on the minus sign. Whenever you want to view the contents of an object, open the object by clicking on its name or icon on the Tree pane. This will display the contents in the Contents pane.
Details view provides the most information about the file.
Click on the headings to reorder the objects in Details view. Moving or Copying Objects Explorer allows you to mark single or multiple objects, and then drag them to a destination folder. Alternatively, you can use the EDIT pull-down menu to Cut or Copy marked files, navigate to the destination, then select Paste to complete the copy or move. Point to the source object and hold down the right mouse button while you drag it to the destination. When the destination is highlighted, release the mouse button and choose either Move or Copy from the shortcut menu.
