The folder structure is hidden in the default view of 'My Computer'. Which means that if you want to navigate quickly, you need to click on the 'Folder' button. Here's how you can speed up the process with a tiny registry hack.

Through the registry, you can set the system is such a way that Windows directly displays 'My Computer' as Explorer with the practical tree structure.

Go to 'Start I Run' and type in 'regedit' Navigate down to the 'HKEY_ CLASSES_ROOT\Folder\shell' key.
Here, double-click on '(Default)' in the right window and type 'explore' in the 'Value data' field of the 'Edit String' dialog box and click on 'OK. After a system restart, you'll be able to directly access the Explorer view when you open 'My Computer'.
